Hi saroroo123,
Glad to hear that it is working. Regarding your questions:
No, this view cannot be hidden.
The remote control is only available on iPad(iPhone’s screen is too small for remote control) and it could only be used under the following circumstances: The desktop client starts sharing, and then give the remote control permission to the iPad user. The iPad user cannot start remote control by itself. Thus it is a passive feature in iOS SDK. In Zoom default UI, you do not need to do anything, if the desktop client provides the remote control permission to the iPad user, the remote control will automatically start.
Hope this helps. Thanks!
