VBA Saveas Addin creates a ppa file instead of ppam

[JMA92410]

Hello,

I create a pptm file and open it
Manually, if I save this file as an Addin, it is stored with a ppam extension
If I run the following instruction in a macro :

ActivePresentation.SaveAs "D:\toto.SaveTest", ppSaveAsAddIn​

This creates a File with a ppa extension

Can anyone tell me how to save a file as a ppam file from a VBA macro ?

Thank you
