Requirement: Get the display name of the Option set( Request subtype), and populate it in the Create task Subject line.
My problem: This flow is created by another person. I can't find a way to recreate it. I can't find the Dynamics content in the red square in my picture. It looks like a normal field as others, but whatever I try to find it, it seems not exist there.. But I want to know how the person initially did that.
