Yamaha musiccast 20 and speakergroup in google home

[frixel]

Hello all,

I am in possession of a Yamaha Musiccast 20 and a receiver Yamaha RX D 485.

I have a Google Nest with a speaker group with the Google Nest and a JBL soundbar.
Now I would also like to place the Musiccast 20 in the speaker group.

Is that possible?
