Help needed with license key

Hi! So, I just installed and activated the Photofocus Pro theme. Per these instructions: https://catchthemes.com/frequently-asked-questions/#question-installation-5 I would like to enter the license key we have. When I click "Appearance => About Theme", no "License" or "License Tab" tab appears so I don't know where to enter the license key. How can I enter the license key or do I need to? Thanks in advance!
