How do I retrieve the pdf of the license file for a stock photo?

Hello, I have purchased licenses for two stock photos (#551290988 and #547905779). I would like to obtain a physical proof (pdf or txt file) of the licenses for the two images. In the license history, I can see the asset numbers and the status that says "licensed", however, I cannot get to the actual license itself. With that being said, where can I retrieve the license file?
