Launch Google Home action from a flow?

I am using Google Home a lot, for example for taking care of all my music, radio, etc…
I just started using Homey as the hub for everything, especially for setting up automation flows.

Now I want to do so that when a flow is triggered in Homey, Google Home should get the question “OK Google, listen to Swedish Radio P4 on home speakers group” (which will turn on the radio station P4 on all my connected speakers).

How can I accomplish this?

Only way I’ve done it is to link Homey to Tasker via IFTT then Tasker starts Google assistant
