I needed to do similar thing on other website.. it not a perfect solution.. but still.. :)
What i did is i recorded like 40-50 scrolldowns till the end of site.. and THEN do all actions.. like in your case.. scrape friends..
Im trying to make a loop where it iterates through list in excel. I need to enter each excel sheet value in a search bar on a website and do certain actions after, for each item in the excel sheet column
