Hey everyone, I'm facing the following issue: I'm using one signal as a push notification service, and I want to create two projects: staging (especially to test some backend notifications) and production. For production, I can attach the .p8 file and then we're good. For staging, if I attach the same .p8 file, I would be in trouble because I can send a notifications to a real user even being on staging environment. How should I proceed in this situation?
