Arknights Welfare RS-EX-3 Clear, Challenge Mode

The Rides to Lake Silberneherze level RS-EX-3, Passing Loop, Challenge Mode, cleared using only Welfare operators.
I worried only about two Emergency Heaters and then powered down on the arts damage, with blocking as needed.
Welfare operators are as defined at:
arknights.wiki...
wiki/Operator/Welfare.
Comments and advice are always appreciated.

Yeah, the positioning of the heaters make it difficult to make neither a safe nor consistent bottleneck, especially with ranged enemies in the mix. I'm also surprised Insider is here instead of Kroos the Keen Glint, as she has an invisibility S1 or a high-aps S2 that pairs well with frequent microstuns.
Great work on the clear!

I found Insider has just a little bit more attack power, especially with his S2. which was needed here.
