  * PROBLEM DESCRIPTION: The OIDC TAI does not allow the         *
  *                      administrator to configure a resource   *

  ****************************************************************
  The OIDC TAI does not allow the administrator to configure a
  resource parameter to send to the OP's token and authorize
  endpoints.
  This may be required if a WebSphere administrator is using an
  OIDC Provider infra-structure that implements resource
  parameters according to OAuth 2.0 specification:
  https://www.iana.org/assignments/oauth-parameters/oauth-
  parameters.xhtml# óÔé¼ Æparameters
  RFC 8707 - 2. Resource Parameter
  https://tools.ietf.org/html/rfc8707
  

Problem conclusion

• The OIDC TAI is updated so that it can send a resource
  parameter to the OP's token endpoint.
  
  The following property is added:
  provider_(id).resource
  Resource parameter to included in the authentication and token
  requests to the OP.
  
  The fix for this APAR is targeted for inclusion in fix pack
  8.5.5.20 and 9.0.5.7. For more information, see 'Recommended
  Updates for WebSphere Application Server':
