After creating an "Admin Service Account" I can't create a portfolio and receive a "403 Forbidden" error. I can't find a way to give access to this functionality to an admin service account although the documentation suggests this should be possible: https://docs.featurehub.io/featurehub/latest/admin-development-kit.html#_create_portfolio

Any guidance on how to achieve this? I would like to create an Admin API key that gives me access to all features to be able to manage the application completely via the API including creating portfolios, apps, features, etc.

Example HTTP call:

POST http://localhost:8085/mr-api/portfolio
Authorization: Bearer XXX
Content-Type: application/json

{
  "name": "My Portfolio"
}

Calling the same endpoint with the token I get when I log in as a user does work.

Thank you.
