Add or edit allowed domains for Embed API credentials

Hi, 

In the documentation on the bottom of page https://developer.adobe.com/developer-console/docs/guides/authentication/APIKeyAuthentication/#understanding-different-uses-of-the-api-key-credential, it says:

"You can configure up to 5 comma-separated domains, use wildcards to club together multiple subdomains and specify any non-privileged port numbers. You can edit these domains any time by visiting your project on the Adobe Developer Console."

But in the console I can't find any way to edit my allowed domains for an API key or add wildcard domains, it didn't work with wildcard or comma-separated?

I also read that I should be able to create up to 10 credentials per service but I can't find a button to create extra credentials either?

Thanks for any help on this!
