Win32::OLE Perl hide window Powerpoint

With Win32::OLE to manipulate Word documents, I generally use the parameter $word->{Visible} = 0; to prevent the Office window to pop-up. The same doesn't work with Powerpoint. I tried also

$ppt->{WithWindow} = 'MsoTriState.msoFalse';

$ppt->{WithWindow} = 'msoFalse';

with no success. Apparently PowerPoint has a different set of parameters. Anyone has an idea how to call it from Perl?

Error:Win32::OLE(0.1712) error 0x8002000e: "Uncorrect number of parameters"in PROPERTYPUT "WithWindow" at
