How to determine which idMso ribbon control ids are supported on Office 365 Mac

On a PC, I can issued this command to tell PowerPoint to arrange all visible windows:

Application.CommandBars.ExecuteMso "WindowsArrangeAll"

Select all Open in new window

If I try this on a Mac I get a run time error 5 (invalid procedure or argument).

Other MSO control IDs do in fact work on Mac such as this one:

Application.CommandBars.ExecuteMso "ShowNotes"

Select all Open in new window

Furthermore, the CommandBars.FindControls method doesn't seem to work on Mac.

So I have a couple of questions:

1. How can I invoke the Arrange Windows function on Mac? (it's in the menu bar under Window / Arrange All, as opposed to the ribbon)
2. Why do some control IDs not work on Mac?
3. Is there documentation showing which controls are/are not supported in addition to this on GitHub? https://github.com/OfficeDev/office-fluent-ui-command-identifiers
