Hello @Egbejiogu,
Thank You for posting your query onto the Forum.
It looks like the feature/action that you’re looking for is not available yet onto the Power BI Report Server. But you can simply export your deck to the Power Point from your Desktop as well as from Power BI Service (If this option is available to you because workspace admin may disable this option and therefore you might not find the “Export to PowerPoint” option in the workspace but still you can export it from your Desktop).
I’m also providing few links below about how you can export it to the Power Point. (If you haven’t checked out yet.) So now I guess these are the only options available to export your report to the Power Point. And also providing a link below where similar sort of query was asked onto the Power BI Community Forum (although it’s quite a bit old) but still there’s no direct solution available for it the way you’ve been looking for.
Lastly, if your report doesn’t contain that many pages then you can take a snapshots manually of your reports and paste them into the Power Point.
Hoping you find this useful and helps you. 
Thanks and Warm Regards,
Harsh
