Set an Expiry Date for a PDF

[HerCorns]

Good day,

I would like to make a PDF file that prohibits editing, copying and printing, and can only be viewed for say 60 days.

I checked out all the permission settings and content editing, copying and printing can be prohibited, but how to include a time limit or expiry date?

Maybe the later is not part of LO, but how can it be done?

Thanks for your effort and time.

Maybe the later is not part of LO, …

It is definitely not a question for LO and therefore out of place here.
