Problem with inserting PDF as object in PP presentation

Hi do you know how to add PDF file as an object in PP presentation?

Its simply not working on my pc.

You may insert the pdf document “as image” (Insert menu; choose link or embed) or you can copy the entire pdf file in your file explorer and then paste into a slide.

It is accepted like another image.

If you do this:

right-hand mouse > Edit with external tool … then a pdf viewer should open.

I found no other sign of having a pdf content…

If you import a pdf document with more than 1 page the import only shows page 1, the other pages are obviously not imported.

Cheers

PS: Be aware that you work on LibreOffice higher version; I tried on LO 5.4.4.2 on LinuxMint-64.
And the above mentioned proceeding is about Impress, not PowerPoint.
