Linking to GOG

I am new to this site but a long time fan of SC FA in general. So, I went out and bought the game via GOG and am trying to follow the directions to link my account to the GOG galaxy client, but I do not see where you can add the code to the feeds so the accounts can link. The screen shot on the instructions on the main page are a little dated and I cannot find the location to enter the code provided to link the accounts (feeds)

any help would be appreciated.

ok, I figured it out.
For anyone else: You have to link GOG account with FAForever using the website, not using the GOG Galaxy client. Once I figured that out, i was able to get it completed.
