Open an app, then send remote commands
I feel there might already be a way to do this, but perhaps I cannot find it.

I would like to be able to open an app e.g. `com.webos.app.hdmi1` and then send a series of remote commands e.g. `"CLICK"`.

My specific use-case is that when I change to hdmi1 I am asked if I would like to turn on the set top box via webos. I would like to be able to open that app and have the set top box turned on, as I can do with the LG remote by clicking 'OK'.
