Connect Sharedpoint site to khoj

I would like to be able to connect a site to get all of the pdf files and automatically sync them on my local deployed version of khoj.
I'd be interested even in helping develop this feature if necessary, with perhaps some help to be guided in the right direction to waist less time.
