I try to set up a new device which is able to use Spotiy functionality over Spotify Web API.
There is a API call https://developer.spotify.com/web-api/get-a-users-available-devices/ where I can get available devices.
The problem is now that there is no call to add a new device to this list. The new device is not my smart phone but an external spotify certified speaker.
Native Spotify application adds the external speaker in an unknown(?) way. I tried to capture some packages with Wireshark which are sent from speakers when using Spotify but I just see some MDNS broadcasts.
Question: Is it possible to add the external device over Spotify Web API? Do someone know how Spotify Application implements this register process?
