I have a next-gen Scrum project.
I've defined my board columns - but the thing is only the last column in the board marks the issue as 'DONE' (the green V mark).
How can I set another column within the board as the 'DONE' one?
For example in the image attached - let's say I want the 'SYSTEM SANITY' status to set the issue as 'DONE'

(so it will catch as progress in the spring progress indication:
)
