How to add tabs and sub-tabs:
Add the unique content by writing your code in the …_screen_content functions. For example,
'user_has_access' => bp_is_my_profile() to
'user_has_access' => true if you want everyone to see subtabs.
bp-profile-tab-and-subnav.php << where is this to placed in the directory?
Copy the whole content of that example file into bp-custom.php.
You can also transform it into a mu-plugin by just adding it some header information.
Once done, you can test the tabs and try to understand how they work. And then apply your own preference.
So I’m guessing — that for each user I want share a unique item I need to edit code?
** The idea is to share information for the each user; but unique to each user.
So 100 users need to access a private link unique to them — I think this process will need one to create a page each time?
The tab exists — But how is content added? I could add ACF as a quick fix; but unique content per user is not option..??
