Hide tab when user is logged in?

Hi,

I’m trying to add a code snippet that hides the tab I created with this plugin when the user is logged in and visiting the product page.

This is the code:

add_filter( 'woocommerce_product_tabs', 'sb_woo_remove_appraisal_tab', 98);
function sb_woo_remove_appraisal_tab($tabs) {

    if (is_user_logged_in())
    unset($tabs['4706']);
    return $tabs;
}

This works very well if I put a tab name like “description” where it says “4706”. “4706” is the tab ID that this plugin created. Sadly it doesn’t do anything.

How do I find out name to put in the code unset($tabs[‘HERE’]);

Would love to solve this, thank you!
