Is it necessary to leave channel when conversation finished?

We have chat between driver and passenger, and when ride is finished we leave chat.
Problem is that we can’t reenter same chat later as unauthorised.
So may be it is not necessary to leave chat?

Hello @Kirill_zhemenskij

Welcome to the Sendbird community!

It is not necessary to leave the chat channel when the conversation is finished. However, if you choose to leave the chat channel, you will no longer receive messages from that channel. If you want to re-enter the same chat later, you will need to be reauthorised to access the channel. If you do not leave the chat channel, you will still be able to receive messages from the channel even after the conversation is finished.

One thing to note here is if there are no users in the channel meaning if the channel is empty then Sendbird removes empty channel by default.
