Arknights Welfare FC-EX-2 Clear, Challenge Mode

What the Firelight Casts level FC-EX-2, Night Patrol, Challenge Mode, cleared using only Welfare operators.
The main strategy here was lots of healers and to deal with the Dublinn Cannoneer Captains as quickly as possible. I used Jieyun for the ones on the right and Lessing for the ones on the left.
Welfare operators are as defined at:
arknights.wiki...
wiki/Operator/Welfare.
Comments and advice are always appreciated.
