I understand how to configure Dialogflow ES with Parameters and Entities, however, this requires the user to specify those Entities in the question.
Is it possible to extract the user's email address automatically (based on the Google Account or Slack Account or whatever the integration that is using the Chatbot) and pass it to the fulfilment webhook?
I would need to use email address as part of the fulfilment.
The user should not have to specify his/her own email address in a question relating to him/herself.
