Realtime with Pusher

I want to broadcast events like “User Logs In”, “User updates Table X” so I can stream a realtime log of activity on my API. This would not be for sensitive data just very high level stuff. Approach I was considering is using pushers php library and pushing data via the queue event on every api call. However I noticed that there is pusher settings in the .env file so was wondering if its built in to some extent?
