How to set link to files column?

Hello! I would like to set many shared links to the board record in the column with the type “Files”. I see such an ability in the web interface but I don’t see such a way to do it from GraphQL API. The only thing I see is to upload the file to but it is not what I need. The customer requirement is to store all files in so I have links and I would like to set them on the board.
