I’m trying to remove a menu item and tried several approaches, but have not had any luck. It was created from a FAQ plugin.

If I use this line:

remove_menu_page( 'edit.php?post_type=question' );

It will remove the main menu, however I only want to remove two sub-menu items contained inside that edit.php?post_type=question URL address.

For the item I want to remove, the path in the URL bar gives me the following:
edit-tags.php?taxonomy=faq-topic&post_type=question
and
edit-tags.php?taxonomy=faq-tags&post_type=question

I have tried several solutions including remove_menu_page and remove_submenu_page to no avail.

What has failed so far:

remove_submenu_page( 'edit.php?post_type=question', 'edit-tags.php?taxonomy=faq-topic&post_type=question');
remove_menu_page( 'edit-tags.php?taxonomy=faq-tags') ;
remove_menu_page( 'edit-tags.php?taxonomy=faq-tags&post_type=question') ;
remove_submenu_page( 'edit.php?post_type=question', 'edit-tags.php?taxonomy=faq-topic&post_type=question');
remove_submenu_page( 'edit.php', 'edit-tags.php?taxonomy=faq-topic&post_type=question');
remove_submenu_page( 'edit.php', 'edit-tags.php?taxonomy=faq-topic');
remove_submenu_page( 'edit.php', 'edit-tags.php');
