Adding Okta as provider in Roles & Permissions plugin V3

I want to add okta as a provider in Roles & Permissions plugin in Strapi V3 . I have updated the plugin according to the documentation but still getting error that provider misconfigured. This is my grant config for the okta

okta: {
      enabled: false,
      icon: 'comments',
      key: '',
      secret: '',
      nonce: true,
      callback: ${strapi.config.server.url}/auth/okta/callback,
      scope: ['openid'],
      authorize_url: "https://[subdomain].okta.com/oauth2/default/v1/authorize",
      access_url: "https://[subdomain].okta.com/oauth2/default/v1/token",
      subdomain: "",
    }

Is this correct or something else need to be updated.
