Disabled share button ver. 4.7

Hello. Is it possible to activate the "share" button? When I enter users, the button is grayed out. Are there any settings or requirements for this? I am logged in as "admin"

What is share button?

I would like to share the device with another user. The "share" button is grayed out in the users tab. Right next to the "group" button

If this is what I think;)

Solved!! Sorry

That's not a share button. It's "Users" button. It's only applicable for Manager users.

Thanks !
