Wordpress no permission redirection to a popup

I am currently using a custom code where if there is no permission, it will redirect to a need permission page. However I would like to transform this to a popup instead of redirection.

Below is the base of my code:

function redirect_users()    {
    //check permission here    
    if( !$permission )    {
        wp_redirect( 'no-permssion-page' );
        exit;
    }
}
redirect_users();

Basically, when users click on any element with a redirect function(a tag, button, etc), it will run a function and then if there is no permission, a popup will appear.

1. I am asking if there is such a plugin that will open a popup based on permission access.

If there is no such plugin, what I was thinking is to create an ajax function and attach it to all a tag. Then check if there is a permission or not before the actual redirection.

Something like this:

jQuery('a').click( function(e) {
    e.preventDefault();
    if (this.href != ''  this.href != undefined) {
        // ajax check permission
        alert(do some ajax anchor);
        location.href = this.href;
    }
});
jQuery('.btn').click( function(e) {
    e.preventDefault();
    alert(do some ajax button);
    // ajax check permission
    // location.href = this.href;
});

2. if there is no plugin, is there a better alternative to the code that I am trying to make?
