Not exactly the same problem, but my wife has been unable to visit my elderly mother in law who lives alone in a different country because of covid. My mother in law has problems from time to time with email, skype, etc. We switched to zoom because my mother in law can share the screen and we can move the mouse, type etc. We were lucky in that we had an acquaintance we trusted in the same town that could install it. But the basic thing is doing a video call a few times a week so they keep in practice and have a cordless phone or cell phone they can use to talk them through getting zoom connected in the first place if they have troubles. It's not quite a slick as solutions like team viewer but I think my mother in law would not be comfortable with us remote connecting anyway. Good Luck!
