How to add speaker volume control to Apple TV

General

I’m successfully using Apple TV integration and have also created a separate entity to control my speaker volume over IR, but I need to switch between Apple TV and Speaker entities whenever I want to change volume. How can integrate speaker valume control with Apple TV integration?

Create an activity, add both entities, map the buttons and create a GUI. Activities are for this purpose.
