Describe the problem you'd like to have solved

At the moment, the GuardianEntity does not seem to support everything the Auth0 Management API supports. In particular, I need to have access to the Put policies endpoint from the management API.

I don't believe it's implemented anywhere else in the library.

Describe the ideal solution

Ideally, this should be implemented as part of the guardian() method.

Alternatives and current work-arounds

I had to work around by using a custom WebClient at the moment, which forced me to add a new dependency.

Thank you!
