Select Channel at the bottom of the list.
Pick between Regular, Private, or Shared channel types.
Select the Team that you'd like to add the channel to.
Give your channel a Name and a Description.
Add any Default members you might want to include.
Click on Create to finalize your channel request.
If you'd like to approve a channel request, simply switch to Channel requests below the search bar on the Requests tab.
