Hi Audelia,
There are no connectors/modules specifically for Mendix to integrate with Microsoft Powerpoint. You could check if there are general API's available and ask this on sites like stackoverflow.
My quick check doesn't seem promising, I do see some Worksheet (probably Excel) API's on Microsoft Graph (https://learn.microsoft.com/en-us/graph/api/workbookapplication-get), but nother Powerpoint specific. Maybe you can copy/paste a file using the Drive API?
Good luck!
Maybe delivering the VBA code will do? Like it’s done here: https://www.linkedin.com/posts/itsmrmetaverse_ai-itsmrmetaverse-future-activity-7069236360431169536-MM2X
With the module Templater for Mendix: https://marketplace.mendix.com/link/component/109927 you could use a powerpoint template and put tokens in it just like you would do with email templates or PDF templates. Do note that for the JAR file that is used in this module is a licensed JAR. But the costs are not that great.
Regards,
Ronald
