kapa.ai I’m facing an issue: when a new user opens the app for the first time, an event called "First Time App Opened" is sent to Mixpanel. However, at that point, no user ID is attached to the event. The identify() function is only called after the user completes registration, which means there's no way to link the first-time open event with the rest of the user's session or activity. I’m looking for a way to associate that initial event with the same user after they've registered.
