Training scripts on GHEC

Hello,

Has anyone tried running the scripts to generate the repositories on an GHEC instance? I have an SSO account and a organisation (with Owner privileges), but somehow it still doesn't work.
I have created a PAT Token and authorised it for SAML single sign-on. Tried providing both `api.github.com` and `github.com/enterprises/` in the `.trainingmanualrc` file. When running the _'Confirm Setup'_ step, this is what I get:
```
Checking if is accessible via the API...
Can't access the organization via the API.
```
Is it even possible to run the scripts on GHEC or I need to follow the steps from the [README](https://github.com/githubtraining/training-manual/tree/main/script#remote-configuration) regarding GitHub Enterprise Server?
