Lifetime of Shared Links in GameLab, etc

I assume if you share a link in GameLab or other lab, it lasts as long as the course section or account in case of projects?

We have middle schoolers starting portfolios and want the game to persist until they are seniors. I could keep the class and/or account active if need be but was wondering what the lifetime actually is.


I am not aware of any expiration dates, but you may want to reach out to for an official word on that.
