Missing information in Onkyo integration

The Onkyo integration does not show the “artist” information when playing music with Spotify connect.
The Onkyo app shows the artists name, e.g. “Nordic Union”

Onkyo

The integration is not providing this information (only media_album_name and media_title):

It would be very nice to have the artists name too.

Thanks!

In the meantime I found out that the following command returns the artist:
onkyo --host NATQSTN

would be nice if this can be implemented in the integration. Thanks
