Set Cart Expiration Interval in WooCommerce 4

Question

So , how do i expire & empty the cart in woocommerce , since the filters are not doing that at all , only increasing the session on some given minutes , which , honestly , i don't know where the hell is used or if is used in any way to clear the cart ?

There is this:

    add_filter( 'wc_session_expiring', 'wc_custom_session_expiring' );
    add_filter( 'wc_session_expiration', 'wc_custom_session_expiring' );

    function wc_custom_session_expiring( $expiry ) {
        return 300; // 5 mins in seconds
    }

Below , you have my code i wrote for a client , just to save you guys some time , the code posted here does update on the expire time if the "delay" given time didn't passed , and the user is still active / buying things on the shop. If the user stops clicking page for more than 5 minutes (you can change in the code) , the next click he will have on the shop , or the next loaded page , the cart will be emptied.

I am using ReflectionClass to quickly read some protected values out of the session class , just right after updating the expire values with the help of the filters.

Please note this plugin is using $_SESSION , feel free to modd it and post your own version here ! Please do also note this : $minutes = get_option( 'expire_option', '5' ); , i used an admin form field (option) setup for this , feel free to add your own .
