Can't log in now that github user is an organisation

I used to have a user on github that i used to create an account here on netlify , logging in using that github user account. This worked fine, but subsequently that github account was converted to an organisation, to which my regular account was a member. This resulted in no longer being able to access the original site, as I can no longer log in with those github credentials.

I have subsequently set up a new site using another netlify account tied to my regular github account and this is working fine, but the original netlify site is still active (but inaccessible), and when i create PRs, it results in a failed set of checks for that site (because it’s using an old xenial image, which obviously i can’t update because I can’t log in), along with successful checks for the newly created one.

is it possible to either retrieve access to the old original netlify team so that I can either edit the configuration, or just remove it entirely?

I believe you can use your email associated with the previous GitHub account to reset password and login.
