People search not possible in top Search Bar

[Thomsch]

We have disabled the chat feature for most of the users in the company. And it's not possible for these users to look for other users in the search bar.

But they can add users to their contacts as you can see here:
(same search as above)

For the other users with chat, Teams and all the other nice features the people lookup works perfectly. Is this a Bug or a Feature? And is it associated with the fact that the CHAT function is disabled?

If the goal here is to prevent users from communicating with each other, take a look at Information barriers: https://docs.microsoft.com/en-us/microsoft-365/compliance/information-barriers?view=o365-worldwide

@Vasil Michev that's not my question.

Question is why don't I see other people in the search bar.

@Thomsch the same issues incur to me. Could you please give me your solution?
