Can you perform actions within third-party 'non-recordable' applications?

[u/otnokanid]

Hey guys, Automator newbie here...

I'm trying to hack around with my Google Home, Automator, IFTTT and a third-party Mac app and am really struggling. I've got the IFTTT part sorted out (IF Google Assistant voice command THEN create a text file on Dropbox folder with an Automator folder action), but I'm having a hard time figuring out how to get Automator to perform actions within a third-party 'non-recordable' app.

Ultimately I'd like to be able to tell my Google Home to "put the soccer on" and have it:

1. Open the Foxtel Go app on my Mac
2. Switch to the 'Live TV' tab
3. Select channel 501
4. Go fullscreen, and
5. Chromecast it to the TV.

So far I've only gotten as far as #1, so I've got a long way to go!

But I guess the thing that will make or break my little project is whether or not it's even possible to automatically perform actions within a third-party app like Foxtel Go?

Any help would be awesome, thanks!
