Toggle agent availability from mobile app

Hi

I am looking for a way to toggle an omnichannel/livechat agent’s availability via the mobile app.
There is nice button in the desktop/web app for that on the upper left.

This newsposting titled rocket-chat-mobile-app-4-8-new-features-improvements states that the ability to do that via the mobile app was introduced in 4.8.

Yet in 4.14, I have searched in vain and no clue where that button could be. Any tipps?

Btw: the article also states, that iframe login is now possible. I can’t get that to work as well.
