Change: You must be logged in to post a comment.

You can use the following snippet to change the comment text, to add this snippet you can use code snippet plugin / or function.php file of child theme

add_filter( 'comment_form_defaults', function( $fields ) {
    $fields['must_log_in'] = sprintf( 
        __( '<p class="must-log-in">
                 You must <a href="%s">SIGN UP</a> or 
                 <a href="%s">LOGIN</a> to post a comment.</p>' 
        ),
        wp_registration_url(),
        wp_login_url( apply_filters( 'the_permalink', get_permalink() ) )   
    );
    return $fields;
});

you can adjust the code as per your requirement.

@developerpaddy this is the code I found as well but for some reason it doesn’t change anything…

If you are using custom theme or a page builder then it will differ so we need to know what theme or page builder are you using.

@developerpaddy good catch. I am using Avada, I’ll talk to them tks!!
