Companion app on iOS - exit map into main menu

Previously on my Android phone, when I was in game and the Companion app would show me the map and in game pages, I could tap the Back icon and get back to the default startup screen of the companion app, with who of my followers is Zwifting etc - so I could give them all a Ride On for example.

Does anyone know on an iPhone how I can exit the Game interface of the companion app when I’m riding? (Other than disabling WiFi so I am not on the same network, as I would like the option to get back into the Game interface should I want to)
