How to Enrich GitHub Stargazer Data with LinkedIn URLs on Clay

Hi, I am just on trial with Clay — checking things out. I have some repos on GitHub. I wanted to enrich a table with the “stargazers” on those repos. So the table is already populated with the stargazers from a particular repo, but when I went to enrich it with LinkedIn profile URLs, nothing happened. The columns are created, but they are blank. Is there a method to just get the LinkedIn URL from the stargazer?
