After closing the cloudbeaver page, the database connection release time can be configured

After closing the cloudbeaver page, the database connection was not released for a long time, resulting in the inability to connect to the database.
I hope that after the cloudbeaver page is closed, the database connection can be configured to release the connection for the required duration

Start by tracing how CloudBeaver handles database connections when a page is closed; the issue does not name files, tests, or an entry point. Determine where the connection release delay is controlled, identify how a configurable duration should be exposed, and verify that connections are released within that duration without preventing later database connections.
