How use messenger button?

Hello!
I’m new to Botpress and webcoding in general. I have some difficulties to integrate Buttons messengers like Call button or even quick replies. I didn’t find clear documentations on how to implement that and where.

Example of code i wish integrate:

{
  "type":"phone_number",
  "title":"<BUTTON_TEXT>",
  "payload":"<PHONE_NUMBER>"
}

Could you help me please?
