Roku Video doorbell connect to new Wi-Fi

My Roku video doorbell & chime SE was already installed and connected to my wifi and worked fine.  Then I got a new wifi provider so now I have to reset the doorbell.  I can't figure out how to get the darn thing off the wall to do that!  Can anyone tell me or show a picture of how to do this?  I can follow the steps otherwise, I'm just afraid I'm going to break it if I keep prying on it with a screwdriver.
