Sorry, as you can guess, this is a sore point with me. Teaching is my job. I refuse to outsource it, and have little respect for those who do.
Students are not school officials. They’re students. They should not have access to the educational records of other students. That’s why FERPA exists-- to guarantee your right to privacy.
Anyway, OP, I would think that this teacher knows you well enough to write a good recommendation. And if the activity is a specialized program with a name and a moderator, then by all means include it.
