channel_profile_apply

# channel_profile_apply

Changes the channel profile name (2–20 Korean letters, Latin letters, digits or _, not starting or ending with _) and/or picture, as the console Profile screen does. Every channel administrator shares them. The picture is a PNG or JPEG file up to 10 MiB uploaded from this computer (the server never receives it or downloads a link): call with image {kind:"local-file", filename, byteLength, sha256}, send the file with the presigned PUT returned under images.image (the console screen link comes with it), then call again with image {kind:"complete", uploadId, parts:[{partNumber:1, etag}]}. Called without confirmToken it previews and returns a confirmToken; repeating the same input with it executes once.
