Hello @inamoro, the issue is now fixed as I pasted a function in my functions.php file, as sent by the plugin creator.
I will leave the function below for anyone facing the same issue in the future as reference:
function ps2id_custom_script(){
wp_register_script( 'ps2id-custom-script', '', array('jquery', 'page-scroll-to-id-plugin-script'), '', true );
wp_enqueue_script( 'ps2id-custom-script' );
wp_add_inline_script( 'ps2id-custom-script', '(function($){
$(window).on("load",function(){
$(document).on("click","#modal-1-content .wp-block-navigation-link ._mPS2id-h",function(){
$(".wp-block-navigation__responsive-container-close").trigger("click");
});
});
})(jQuery);');
}
add_action( 'wp_enqueue_scripts', 'ps2id_custom_script' );
