I use Teamviewer for supporting my mother over a 550km distance with any PC issues she may run into. I would like to do likewise with her iPhone, but of course, I am aware of the iOS limitations by design.
As my mother is also visually handicapped, I was looking for a "one click" shortcut for starting TeamViewer and screen sharing, but couldn't find anything among Apple's own shortcuts nor with ITTT.
Is anybody aware of anything usable in this context? Her iPhone and Siri have become my mother's primary communication channel, so finding a solution would be extremely appreciated.
