Exam Certified Tableau CRM and Einstein Discovery Consultant topic 1 question 62 discussion

A client has a dashboard for Sales Managers. They want to have a list filter that shows the name of the month. However, based on the "CloseDate_Month" field, the list filter shows numbers instead of names.
How can a Tableau CRM Consultant use the Dataflow nodes to generate the name of month as a new dimension in the dataset?
