Deleting channel

[JerryId]

When I try to delete a channel, the user that belongs to that channel is also deleted. Then when I watch (or create) a new channel with the same user, I get the following error:
Error: StreamChat error code 4: GetOrCreateChannel failed with error: "The following users are involved in channel create operation, but don't exist : [...user_id]. Please create the user objects before setting up channel."

Here is what I want to do:

• I want the app to behave just like in Facebook (messenger) where deleting a channel will also delete all the messages that is included in that specific channel.
• Then creating a brandly new channel with the same user should work correctly without the above error.

(I used the same code as describe in the official docs for deleting a channel)here.

Does anybody know how to fix that issue ?
