Provide Group/UnGroup functionality in PowerPoint JS API

Hi Troy-

Thank you for requesting this feature and thanks to others for upvoting it. We released functionality in preview earlier last month. You can find that here. https://learn.microsoft.com/en-us/javascript/api/requirement-sets/powerpoint/powerpoint-preview-apis?view=common-js-preview

Please try it out!

Thanks for your patience!

This is needed to access all the objects.  This is also true for other Office document types.  Otherwise, we will be forced to fall back to older apis.

Hi Troy-

Thanks so much for sharing this! I've noted the request to be added to the backlog for PPT APIs.

Thanks!
