How to Avoid Duplicate Enrichment of LinkedIn Person in Table

How can I avoid enriching the same linkedin person twice (I have a table of linkedin posts so some of the rows have the same author)?

Hi Matias, I think the quickest way in this case would be to export the table as a csv, then filter and remove duplicates in the owner url column, export back all the unique values in a new table, enrich them, and them perform a lookup to add all the values to the original clay table when there is a match with the url.
