Only allow admins to create new streams
Note: This feature can only be controlled by organization administrators.
By default, any user can create new streams. You can enable a setting that only allows administrators to create new streams in the organization.
Select the Prevent users from creating streams checkbox under the Streams & custom emoji section.
Type a number in the Waiting period for stream creation (in days) input to specify the period of time users must wait to create a new stream.
Click on the Save changes button to save any changes you made to your organization settings.
