license field missing

I just bought GeneratePress premium and got a receipt for it, but I can't find where on the site to enter my license key. I went to the WP dashboard, Appearance, Generate Press, which is where I can choose the modules I want, but there's no place to enter a license key.

Maybe the key is just for updates, but I want to start building new pages with GP and Elementor immediately. My site is half built and I want to finish it. I switched from OceanWP to GeneratePress just today.
