kids rearview mirror

I searched online and on subreddits but didn’t find what I was looking for. I don’t want to replace the rearview mirror which is fine in my opinion. I have two kids on back and sometimes I’d like to check on them (laughing at my dumb jokes, sleeping, eye contact, etc). Searching online only brings rearview replacements, but I want an additional one.

I saw some with a succion cup but I’m not sure it’s good (first, steady, and second, angle of view if hooked on the roof). I’d have hoped to have one convex to be panoramic, and hooked on the bar between the roof and windshield. Has anybody tried that? Pictures would be great

Thanks
