We are trying to use Salesforce Surveys within a Journey builder. We enabled and created a survey through salesforce survey, but we don't get how such survey should be sent via journey builder.
We followed the instructions on this doc page: https://help.salesforce.com/articleView?id=task_use_survey_marketing_cloud.htm&type=5
That way a record in the SurveyInvitation link gets created, but the actual invitation link never gets sent to contacts who are in the journey.
I'm missing something here. How can I accomplish this? Can't really find anything on the web.
