Do you find the "Pointer Options" as following?
If you have choosen the "Arrow", but it does not work, or you could not find the "Pointer Options", I would suggest you uninstall PowerPoint for Mac, that move the icon of PowerPoint to Trash, and then download the package from the article "Update history for Office for Mac" according to the Office version number.
Such as for Version 16.54 (21101001), you could choose the one highlightered on image below to download.
To find the version numerb of Office, please refer to "About Office: What version of Office am I using?".
Any updates, please feel free to post back.
