I am looking for a way to provide quick responses for the users during a dialog where the user can quickly respond by selecting one of the provided responses.
After searching I found this for Dialogflow ES but unfortunately I am using CX.
For the Dialogflow Messenger you can define custom payloads to add buttons or suggestions chips (which actually sounds exactly what I need) but I have no clue how to actually provide a response which acts as an intend for the dialog.
As I mentioned in comment section, Dialogflow have a 3 Editions - Trial, ES and CX
Trial:
A free edition that provides most of the features of the standard ES agent type.
ES:
The Dialogflow Essentials (ES) Edition is a pay-as-you-go edition that provides the standard ES agent type.
CX:
The Dialogflow Customer Experience (CX) Edition is a pay-as-you-go edition that provides the advanced CX agent type.
