I want to implement Firebase's Firestore Functions like onCreate or onUpdate but I would like to know if it actually supports other programming languages other than JavaScript or TypeScript for such purposes? I've done some research, most people say Firebase now supports other languages but I think they're confused with GCP (Google's Cloud Platform) which is a different service suite. Also I can't find any tutorial related to implementing Firestore Functions in other languages.
If Firestore has not really support other languages yet, does Firebase Admin SDK has some workaround that's similar to Function's onCreate?
Thanks!
