Ios build failing

Error while building the game. Check the logs of the build for more details.

Signing options not set up

I get this message when I try to use the new iOS build tool.
Do I need a valid Apple developer ID associated some how?
How do I find the 'logs of the build"?
“Signing Options not set up” what does this mean?

Please read the documentation:

I figured out that I needed a gold subscription, but only had silver. Once I upgraded, I then realized I need my Apple developer account working properly. I have been having issues with Apple getting “enrolled” for some reason.
I should be good to go once I am enrolled.
