   * Upload File
   * Upload any file from Windmill object storage. With `channel` it is shared there (with an optional `initial_comment`, or as a thread reply with `thread_ts`); without it the file stays private to the uploader. Uses files.getUploadURLExternal + files.completeUploadExternal. Needs files:write (bot default; tick it for a user token); a bot must be in the channel.
