Hi, I'm giving a ContactId, an AccountId and a collection of AccountContactRelation records as input to my action button. The idea was to have a subflow that outputs the record of an account contact relation so that I could get the multi select picklist that I want to add in the screen flow as a multi select picklist field but the record output variable wasn't showing as an option when adding a multi select picklist field to the screen.
The second thing I tried was to add a multi select picklist component to the screen and then define the choices returned by the action but the same happened. I can see the right multi select picklist values returned by the action in a display text, I just want to put them in a multi select picklist in the screen so that the user can change them.
For a little more context, I'm doing this in one screen because the user selects in a picklist the account (Contact -> Account relation) that he wants to change the multiselect picklist values.
Thank you
Have you tried using a collection choice set that uses the output of the screen action as its data?
