error when using $bp->displayed_user->domain

[locker17]

Using $bp->loggedin_user->domain like described here:
<a href="​https://codex.buddypress.org/developer/the-bp-global/">​https://codex.buddypress.org/developer/the-bp-global/</a>
throws an error on my page:
Undefined property: stdClass::$domain

So I am using the function bp_displayed_user_domain() instead which works. I am running PHP 8.2 if that matters.

If $bp->displayed_user->domain is deprecated or whatever can someone please update the docs?
Thanks!

Reason: Tried to use $bp->displayed_user->domain when testing this script here from shanep to add a new tab:
