Adjusting Realtime Presence Heartbeat Rate

I'm working on a project that requires more frequent updates of user presence in a room. In my case, it is used to monitor if an user is still well connected to the app or if he add an issue. The nature of the app make a need of "real realtime" where 1min delay before knowing there is an issue with a user is a big deal.

Currently, I'm using Supabase Realtime's presence feature, but I need to detect changes in user presence more quickly than the default behavior allows.

Specifically, I'd like to be able to determine if a user is present in or has left a presence room within a 3-second timeframe. From my understanding of the Realtime protocol documentation, it appears that the default heartbeat occurs every 30 seconds.

Potential feature needed:
Adjust the heartbeat rate to a shorter interval. It would probably be a setting in the dashboard.
