access groups with nested OIDC claims

Hi, I would like to create an access group in Cloudflare Access based on an OIDC claim that is stored within an object inside an array. For example:

{
  "email": "[email protected]",
  "oidc_fields": {
    "sub": "user-unique-id",
    "role": [
      {
        "description": "role description goes here",
        "teamId": "abcd/3412"
      }
    ]
  }
}

{
  "email": "[email protected]",
  "oidc_fields": {
    "sub": "user-unique-id",
    "role": [
      {
        "description": "role description goes here",
        "teamId": "abcd/3412"
      }
    ]
  }
}

I would like to create a rule so that only users who have a specific role description and belong to a specific team will be part of the access group. Users can have multiple roles in various teams, which is why it's an array. I don’t have control over the service providing these values, so I can't change the user identity structure even if I wanted to. Is it possible to access the claim in the "Claim name" section in this case? Thanks in advance for any help!

sadly the documenntation for custom oidc providers is pretty barebones and doesnt cover this, i had the same question when i was building out a custom provider and ended up doing what you cant (changing the claim structure) if this is possible then its not documented, so i wouldnt know how to do it
