-- Lists all Channels created under a single Chime App as a paginated list.
-- You can specify filters to narrow results.
--
-- __Functionality & restrictions__
--
-- -   Use privacy = @PUBLIC@ to retrieve all public channels in the
--     account.
--
-- -   Only an @AppInstanceAdmin@ can set privacy = @PRIVATE@ to list the
--     private channels in an account.
--
-- The @x-amz-chime-bearer@ request header is mandatory. Use the
-- @AppInstanceUserArn@ of the user that makes the API call as the value in
-- the header.
