Child Lock at Lightroom mobile to deactivate editing functions for view mode only

Hello, everyone,
I always have the situation that I spontaneously show the family current photos with Lightroom Mobile on my iPad, e.g. the pictures from the last vacation.
I think most Lightroom users use their library for this.
Now the viewer starts swiping to the left, right, up and down and, since he is not familiar with the Lightroom program, adjusts my star ranking, sets flags, etc.
I get a heart attack every time Grandma changes my ratings or even rejects the picture. 🙂
What I would really like, would be a simple "child lock" where you can completely deactivate all editing functions, i.e. safe browsing and viewing of the photos is possible when children and grandma are browsing through the albums. Does such a function already exist? I've searched all possible settings but found nothing like this. The slide show doesn't help me here, because you jump through the pictures randomly and look at the pictures for different lengths of time.

I would be very happy about your ideas! If this function does not yet exist, an implementation in one of the next releases would of course be awesome!
Thank you until then!
