Slides as Background - Can't load because "don't have" Keynote or Powerpoint (but I do)

[qeldoq]

I wanted to try out the Slides as Background functionality.  I know it's still a beta.

I chose the option in the Advanced Screen Share window, and the error messages said that it couldn't open the file because Keynote (or Powerpoint) is not installed.

I have both, I use them both all the time.

Screen grab with the error attached.

Is there something that needs to be done to "turn them on" for Zoom to see them, or somehow specify where they are (in the Applications folder, the default location), etc?

Thanks!
