Guide for using Siri with this plugin, especially with switching Activities?
Hello - I looked for documentation and through the other issues but didn't find a definitive list - how can I use Siri to control Activities set up with this plugin?

I have the plugin configured to expose Activities as a TV Accessory in Homekit. Say the hub is named 'Harmony' - I see a TV device named Harmony in my Home app, with the activities listed as input.

I can successfully say 'Turn on Harmony' and 'Turn off Harmony'. 

I'm unable though to switch inputs via Siri no matter what command I try to give. Say I have 'Play Playstation' and 'Watch Apple TV' - no combination of 'Play Playstation on Harmony' or 'Play Playstation on Harmony TV' will work.

I'm assuming I'm missing something here, so any guidance would be appreciated - can turn that around into a PR to improve the documentation as well.
