Meeting shortcut on iPad

[Starfishzippo]

I'm looking for an easy solution for my 92 year old mother who struggles every time we want to contact her.  

I have created a Shortcut on my mother's iPad to take her to our usual meeting with one click and embedded the meeting link URL in the Shortcut but when she uses this it only gets her to the Zoom meeting selection as if she had clicked on the Zoom icon. It does not bypass the Meeting ID and Passcode as it would if she clicked on the URL in an email for example. Is there a way to access the meeting in this way without having to enter everything?

Also, is there a way to default the Audio to Computer so that she doesn't have to select that either?
