WordPress login hooks – how to make login redirect in correct behavior?

Hello everyone!
In a polylang’s 5-languages website I am using WPS Hide Login plugin and Ligin/Signup Popup plugin. So for login and logout I have to manage correctly behavior in those two scenarios:

• 1°) I am in my country and I use the website in local language which is browser’s one;
  2°) I am in another country and I use the website in my language selecting anguage by Polylang so that means like :
  pll_current_language() != substr($_SERVER[‘HTTP_ACCEPT_LANGUAGE’], 0, 2);

Having WPS Hide Login settled without any redirection fields settled and Success Endpoint deactivated to manage by language I reached to manage logouts correctly between those two scenarios to redirect to homepage with logout_url hook:

function my_logout_redirect($link) { 
    
    $session_lang = pll_current_language(); 
    $browser_lang = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 2);

    if ($session_lang != $browser_lang && ! is_admin() ) {
        $redirect_url = "https://example.com/wpshidelogin/?action=logout&redirect_to=https%3A%2F%2Fexample.com%2F" . $session_lang . "%2F" . "&_wpnonce=" . wp_create_nonce( 'log-out' );
        return $redirect_url;               
    } 
    if ($session_lang == $browser_lang && ! is_admin() ) {
        $redirect_url = "https://example.com/wpshidelogin/?action=logout&redirect_to=https%3A%2F%2Fexample.com%2F" . "&_wpnonce=" . wp_create_nonce( 'log-out' );
        return $redirect_url;
    }
    if (is_admin()) {
        $redirect_url = "https://example.com/wpshidelogin/?action=logout&redirect_to=https%3A%2F%2Fexample.com%2F" . "&_wpnonce=" . wp_create_nonce( 'log-out' );
        return $redirect_url;
    }       
    return $link;   
}
add_filter( 'logout_url', 'my_logout_redirect', 10, 3);

but to manage login, redirecting to homepage once logged, it looks like a bit messing up using this code:

function my_login_redirect( $redirect_to, $request, $user ) {
//function my_login_redirect() {
    $session_lang = pll_current_language(); 
    $browser_lang = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 2);
    $redirect_url = "";
        
    if (!is_admin()) {
        $redirect_url = "https://example.com" . ( ($session_lang != $browser_lang ) ? $session_lang : "" ) . "/";
    }
    if (is_admin())
        $redirect_url = admin_url();

    /*
    if ($current_language == "it" && $current_language != substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 2) && current_user_can('administrator') == false) 
        return "https://example.com/it/";
    else 
        return "https://example.com/wp-admin";
    if ($current_language == "en" && $current_language != substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 2) && current_user_can('administrator') == false) 
        return "https://example.com/en/";
    else    
        return "https://example.com/wp-admin";
    if ($current_language == "es" && $current_language != substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 2) && current_user_can('administrator') == false) 
        return "https://example.com/es/";
    else
        return "https://example.com/wp-admin";
    if ($current_language == "fr" && $current_language != substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 2) && current_user_can('administrator') == false)     
        return "https://example.com/fr/";
    else    
        return "https://example.com/wp-admin";
    if ($current_language == "de" && $current_language != substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 2) && current_user_can('administrator') == false) 
        return "https://example.com/de/";
    else
        return "https://example.com/wp-admin";
    */
    
    //return home_url();
    //wp_safe_redirect($redirect_url);
    //exit;
    return $redirect_url;
}
//add_action('wp_login', 'my_login_redirect');
add_filter( 'login_redirect', 'my_login_redirect', 10, 3 );

where it always goes to login page (yes, as login page I created a page with [xoo_el_inline_form active=”login”] shortcode since I use Login/Signup Popup plugin for login/logouts…. even if I log in in admin panel it goes to Login page instead of wp-admin…and I got stuck at this point… Any suggests? If needed , I can provide more informations about behavior happens on my website with this login_redirect hook….

Thanks in advance! Cheers
