Add Template to Confirm Appointment (Details)

Im trying to create a template for “Confirm Appointment (Details)” and I want to have the current info it displays:

  • Title: “Details of your booking”
  • The form with the start and end date, etc
  • On the left side a block with the selected listing

How can I add the default information?

Thank you

I found it out, you have to save the template first then the avaliable widgets for the selected template will appear
