Configure 3 Music Player Daemons

I have 3 Moode Audio Players, each of them I can configure perfectly according to the instrunctions here: Music Player Daemon (MPD) - Home Assistant (home-assistant.io)

But I have no clue on how to configure all 3 of them so they function at the same time.
Any help would be appreciated

Go to Settings ==> integrations ==> helpers ==> group ==> then choose “media players group” and add all the three MPD entities to combine into the group.
