OptionalplaylistPlaylist index when the host first handles the request. Required unless playlistGuid is supplied; use the GUID to preserve identity across that initial queueing delay.
OptionalplaylistPersistent unique identifier of a playlist (bracketed GUID, case-insensitive), used in place of a mutable index. Mutually exclusive with playlist; passing both or an invalid format fails with INVALID_PARAMS. Fails with NOT_FOUND if the playlist does not exist, never falling back. Invalid-format and not-found failures return the given GUID in details.playlistGuid.
Parameters for
playlist.showAutoplaylistUI. Accept a request to open the native editor of an explicitly named autoplaylist. Give exactly one ofplaylistandplaylistGuid. Acceptance precedes the queued native call; its normal return or failure is reported byplaylist:autoplaylistUIResultto the same calling document. Subscribe before calling because the event can arrive before the acceptance promise resolves. The request does not activate the playlist or start playback. A normal native return does not report whether a window appeared, the user saved changes, cancelled, or closed the editor.
