Can I set the maximum duration of a session

[qianjunhu]

We have two questions about the application. Can you help us?

1. When we enter a meeting in Room call mode, is there a time limit for the meeting? If yes, what is the maximum duration? Can we customize the settings via sdk?
2. When there is only one participant in a room, if no new participant joins the meeting and the existing participant in the room does not close the meeting voluntarily, how long will it take for the meeting to end? Or does the meeting never end as long as there is a participant in the room?
