Anniversary/Birthday flow each year
I have a list where users are added to daily.
I want to sent them a birthday mail each year 21 days before the birthday. The only value I have is a "date of birth" (incl year)
I can see some other cases with same type of issue where a trigger "request campagin" was suggested.
My question is, if my flow looks like this, isnt it correct that this will only sent ONE birthday-mail 21 days before the date of date(current or next year).. but not recurring each year in all future?

Do I then need to "request this campaign" one time each year?
Or can I as a last step in the Flow, request it self?
