S2 Member + BuddyPress - Nav Menu Control

Hi, there is a video in S2 Members KB articles which describes how to create custom nav menus for BuddyPress. The plugins he mentions are not longer supported. Does anyone know of another (hopefully not too complicated) way to go about this?

I googled it and followed the instructions of this article - https://themekraft.com/customize-profile-and-group-menus-in-buddypress/

I created a bp-custom.php file under public_html > wp-content > plugins > buddypress. I added the code in the article exactly as it is written and only changed the names of the menu items. When I clicked save & refresh (and delete cache & history) nothing changed. It was like I didn’t do anything at all.

Is there something I’m doing wrong?
