People on HackerOne keep reporting this file as containing a secret token.

The reality is that this token is no longer usable since it was
published to a public repo, which would have caused it to be revoked
automatically though GitHub automation:
https://docs.github.com/en/code-security/secret-scanning/about-secret-scanning

Other than that I'm pretty sure nobody is using this script.
