web access – download all the files (pdf, doc, xls..etc _no photos) of a Facebook group just by putting a corresponding group link

I belong to many groups on facebookand in many of them many files are uploaded daily, it is possible with mathematica to download to my pc in a “group” folder all the files of a particular group of which I am a member.
Downloading them one by one delays the process if there are many, on the pc I can review them much faster

I have searched long in the previous questions but I can’t find anything like it
The link of a group is in the form https://www.facebook.com/groups/abcdefghijklmnop/files where abcdefghijklmnop are 16 random digits
