Any suggestions for a new revert needing to pray secretly at school?

Assalamu alaikum everyone, I'm a fairly new revert currently being homeschooled but switching to in-person school next year. Since I live in an area of the US where practicing openly might be risky, I plan to keep my reversion private from classmates and teachers. My main worry is finding a spot to perform my prayers during school hours without drawing attention. The school does have private, gender-neutral bathrooms, but honestly, I'd really prefer not to pray there as they're not the cleanest. Any advice on what I could do? Should I just approach a teacher, administrator, or counselor about this, or is there another discreet option?
