I know I can use the API command https://api.spotify.com/v1/search
to get a search result in an JSON string.
But can I use a Spotify API command to send a search query to the player and get the result in the player itself?
Seems like spotify:search:<search_term>
works.
Try something like spotify:search:the%20rolling%20stones
in a browser. It should link you to the app, in the search section. (Tested on macOS and iOS and it works)
