I'm trying to implement an invite-system, where each invite has an expiration-date, and a status that tells me if the invite is still pending, or already expired. right now, I'm computing the value for the status field in my custom resolver based on the expiration-date, which works fine, but I'd rather like it to update the status in the prisma backend based on a timer. how'd I go about doing this? or is this maybe not recommended?
