New aser ring video doorbell

bought the inlaws a doorbell for christmas got it all fitted and working and connected to Alexa all works fine but the only thing that is bothering them is when the bell is pressed you cant open the app without entering the passcode on the phone unlike a normal phone call .Is there a setting i am missing are is this the norm its a bit of a problem for them as they are quite old and have bad athritus in their hands
