The `openid-connect` plugin does not set the `audience` form parameter with `client_credentials` auth method

I am trying to configure the client_credentials authentication method with the openid-connect plugin. My IdP (for example Auth0) requires that an audience form parameter is being sent when using the client_credentials authentication method so I have configured the config.audience parameter in the plugin configuration.

However, authentication still fails with the following error suggesting that the parameter is not being sent:

{“error”:”access_denied”,”error_description”:”Non-global clients are not allowed access to APIv1"}

Setting the config.audience parameter in the openid-connect configuration options does NOT cause the plugin to add the required form parameter.

Please use the config.token_post_args_names (Config.Token Post Args Names in the Kong Manager UI) and config.token_post_args_values (Config.Token Post Args Values in the Kong Manager UI) configuration parameters to correctly set the audience parameter.

An example of the relevant configuration would be:

 "token_post_args_names": [
      "audience"
    ],
"token_post_args_values": [
      "https://<audienceURL>"
    ],
