I need to remove/hide extra admin pages

I'm working locally at the moment but I am testing the Membership plugin for a client. It works well (so far) and seems to be what we need. However, there are a lot of extra admin pages that my client does not need or want and I'd like to hide them (without the use of another plugin or editing the plugin).

I would typically put something like this in my functions.php file:

function remove_membership_admin_pages() {
	remove_action( 'init', 'M_Ping');
}

add_action( 'after_setup_theme','remove_membership_admin_pages', 100 );

Unfortunately, I'm not sure how the admin pages are called. I want to remove Coupons, Communications, URL Groups, Remote Pings & Payment Gateways. We only have 1 membership level (free) and the remaining admin pages just add to the confusion.

Can someone help me with this? Thank you!
