Media_player present in Spotify for playback?

Hi, is it possible to see in this Spotify list group →


my “media_player” group i created ??? (contains my google nest mini and my sony bravia android smart TV)

In a nutshell, I would like my group “media_player.assistenti_tv_google” to appear in the spotify list so that by selecting that group, music from Spotify will be played throughout my house.

p.s. Many of you will think “just create a group of speakers in Google Home” Yes, ok for Google Nest mini it works, but the smart TV does not appear in the list like the Chromecast, so I have to do this stuff here just to incorporate the smart tv
