Delay in user refresh in the drawee project

I worked on a project based on YJS this time.

The URL is Drawee - Multiplayer drawing game website! , and it is a multiplayer drawing game based on WebRTC.

There was a particularly difficult part during the project, and it still remains unresolved.

There was an issue where if a user disconnected, they couldn’t reconnect again, and the connection was not established when they tried to re-enter.

When I opened the code, I found that the refresh rate was set to 30 seconds.

Is there a way to solve this issue?
