Is it off-topic? As a 1st party plugin I considered it on topic, however I see it being closed as a 3rd party plugin question, and there is no question to give an authoritative yes or no on the meta stack.
If the question was about WooCommerce or another 3rd party plugin then yes it would be off topic, but BuddyPress is 1st party like the twentytwenty theme or the gutenberg plugin.
What is our official policy regarding questions about BuddyPress?
Note: This is specifically about the official BuddyPress plugin at https://buddypress.org/, not the extensions/themes/add-ons/other 3rd party code.
