What's best way to turn on my Shield w/ voice (multiple actions)

I can turn on my shield with Google Assistant “ok google, turn on shield”
I can start Music paying with my Kodi/node.js webhook integration “ok google, toggle party mode”
How can I combine those to 1 command that will 1st turn on the shield, then start my music. Can I do a webhook directly to HA or Google maybe? All the devices are already integrated into the dashboard on HA.
