Ways to find prospects through Facebook groups question

What are some ways you guys use to find prospects or groups to join on Facebook, There used to be a chrome extension that I was aware of but no longer works and just looking for some options or tools to help out other than manual search input on facebook.

Create your own script that will search for keywords and scrape the group results into various categories. Pay someone $5 an hour to manually sort through them and save the ones that look high quality (decent volume, decent activity and related to niche) and then use those. Quality over quantity.

Make sure that you are using the right keywords for your niche when searching for Facebook groups. If you really want to find "quality" prospects, join groups that have paid membership. These are filled with customers that you would want to connect with because they are willing to invest in premium services/products.
