How to redirect returning users who previously logged in?

Question

There are many answers to how to redirect after login. But my situation is different. In my scenario, we have a landing page where people can login. Once logged in, the users are not logged out for a year. So, what we want to do is, when the user visits the site, check if they are logged in. If they are logged in, automatically redirect to a specific page. I used a plugin to embed this code on the landing page, but it does nothing :

<?php
if (is_user_logged_in()) {
wp_redirect( 'https://our.domain/specific-page/' );
exit;
} 

Edit: I added echo statements before entering the if block, after entering the block, after calling wp_redirect, and, after exit. When I look at the page source, all the echos are printing, except the one after exit.

I'm not very experienced with PHP, but I suspected this has something to do with headers. If I embed the script in a page, it is trying to redirect AFTER the page is rendered. So, I used a plugin called Code Snippets to add this to the functions.php:

function my_custom_function() {
    if(is_front_page()){ 
        echo "before the block";
        if (is_user_logged_in()) {
            echo "user is logged in";
         wp_redirect( "https://my.domain/page/");
            echo "after redirect";
          exit;
            echo "after exit";
    }
}
}
add_action( 'wp_enqueue_scripts', 'my_custom_function' );
