Please point me toward some AppleScript Source code examples for macOS TV.app

These links were not 100% helpful.

However, I pushed through the Script Editor's Guide and bumped into the Log History window - Window --> Log History

Keyboard Shortcut Command-Option L

That window provided the debugging details I needed to see what I was messing up on.

So here is a sample script that works on Catalina :

tell application "TV"
	activate
	
	try
		set sel to selection
		if sel is not {} then
			repeat with aTrack in sel
				display dialog "Name: " & (name of aTrack) ¬
					giving up after 5
			end repeat
		else
			display dialog return & "No tracks are selected..." buttons {"Cancel"} ¬
				default button 1 with icon 0 giving up after 5
			return
		end if
	end try
end tell
