Copilot Enterprise

Body

I was using the github copilot free version successfully.
Now I updated to github copilot enterprise subscription and I get this problem.
Copilot not usable in intellij since then.

I am successfully logged in into github and can see the green ready icon in the right bottom corner.

But, my agent is only showing "sign in for github copilot"

added log file: log.txt

most interestign part:

found the solution. My organization did not enable github copilot for ide integration. After that was enabled and the models, it worked.
