Hi,
I am using the DF CX Messenger integration and noticed there is a JavaScript function to set additional query parameters (https://cloud.google.com/dialogflow/cx/docs/concept/integration/dialogflow-messenger/javascript-functions#setqueryparameters). I have used this and I can see query parameters been sent over the network, but how do I access these in Dialogflow CX? I thought I could use $session.params.<parameter_name> but this doesn’t seem to work.
Can anybody advise please?
Thanks!
