Mobile phone adapter to attach to a stereo microscope

Anyone found a decent adapter that isn’t cumbersome to mount on a microscope? I see a lot of complaints that it’s hard to line up the phone camera up with the microscope eye piece–maybe somebody has foud one that works? Saw one on Amscope, but with similar complaints: https://amscope.com/products/ad-tmd

This would be for student lab purposes looking at magnified insects, plants etc. I found a compound stereo microscope that I like, but ideally students could take a picture of what they see under the microscope with their phone camera and post it to iNat. Thanks!
