Help with filter for the catalog-backend-module-okta plugin

[wywilliamyang9]

The following is the current config I have in the app-config:

providers:
    okta:
      - orgUrl: 'https://fico.okta.com'
        token: ${OKTA_TOKEN}
        groupFilter: profile.name eq "Backstage_Users"
        schedule:
          frequency:
            seconds: 20
          timeout:
            minutes: 10
          initialDelay:
            seconds: 45

It is pulling only the group Backstage_Users and pulling all the users in my org. Ideally, I want to pull only the users in the group Backstage_Users and all the groups in okta so the users can be assigned to the groups that they are assigned to in okta. Could someone help with this? For the userFilter, I tried memberof eq "Backstage_Users" but that is not valid.
