Is there anyway to recover or archive a project from an old classroom?

About 2 years ago i was in a coding camp with some friends and we made a game using cospaces. It was some really stupid game about a ton of things we found funny but it’s pretty nostalgic for me and reminds me of some of my best memories.
We were in a class room when we made it, and we didn’t archive it or anything. We aren’t in the classroom anymore, meaning we don’t have access to it either.
I’m just wondering if there is any way for me to view this project again? My user name was TheCarlWheezer and i saved the original URL on a USB stick: CoSpaces Edu: Make AR & VR in the classroom

If anybody could help I’d really appreciate!

It’s easier when we’re talking about Google Classroom, but the files are not retrieved but it was pretty possible before. But I think you can find the files in Classroom folder on Drive, so you can use Google as an option.
