Looking for Documentation on Modern Player Regions and Tools

I'm working on matching navigation instructions with what screen readers announce for the modern player interface. Does anyone have a comprehensive list of the names for each region and the tools contained within them?

For example, it sounds like the "miscellaneous controls region" includes settings and playback speed options, but I'm figuring this out by listening to the screen reader.

If there's official documentation or any detailed list available, I’d greatly appreciate it! Thanks!
