Open Tasker on Android TV setting page opening

I tried Tasker on Sony Android TV, I want to quickly open a level control setting page that has the Digital Output Level Control, that can only be accessed after many remote control buttons pushes, making it inconvenient for changing the volume level.
1- I tried App Opening in Tasker, used ALL option, and tried all available apps a,d those accessed by long press, did not find one related to it.
2- Maybe there is a hidden package name not included here, if there is, How can I find it?
3- I tried Custom Settings to change the digital volume directly, but could not find the corresponding setting.
4- I am not sure if Android TV operates strictly on Android system, or it still has it's own internal system for some options but with Android interface, but still if the Android interface can access it, Tasker should be able to do that, right?

 

is there a way to monitor in Android which activities are opened , or opened lately , ?

 

Great, Thank you I will try and let you know

 

I tried it, I got an error
Error: 1
Could't get current app info

 

ok, I managed to give Tasker permission to read Application activiy permission using the built in Tasker Permission grant task.
and the Task run correctly and reads the app and activity name.
Now I got to 2 new problems level:
1- Tasker reads same names when I open the main Sound Page, and when I open the sub popup window of the level inside the Sound Page
2- When I create a task to open an App, and insert the name I got from reading the App or Activity names, I get an error
Launch app: Failed to Run
