Automation Using HomePod with Music Assistant

First of all I want to give all of the devs a sincere thank you and congratulations on Music Assistant 2.0, what a huge feat and so far has been the exact integration I need for what I want to do.

I am creating automations that send radio stations via URL using MA to my HomePods. I trigger this by exposing an input boolean to HomeKit and it works very well, with the speaker I write the automation to. The problem is if I trigger the automation with a HomePod in a different room it will only play in the bedroom.

Is there a way to grab the device entity on the HomePod I am talking to and then pipe the streaming radio station URL to that one?

Essentially, how can I find out which HomePod hit the switch?
