Linking API Org to ChatGPT Enterprise Org

I may be doing this wrong, but I’m trying to get my account on platform.openai.com to link with my account in my ChatGPT Enterprise account. I’m not sure why they are showing as different to start with?

Whenever I’m using my API key to query things in my Enterprise account it’s saying user not found, since obviously the two orgs are different.

Has anyone else successfully done this?

Thanks
