How to Aalto - 100% Tales from Mt. Firmament event completion - Lvl. 120 bosses!

Wuthering Waves 1.1 - The event "Tales from Mt. Firmament" requires two level 120 enhanced bosses, Construct: Protective Scales and Mighty Lightcrusher, to be killed for 100% completion. I found that Aalto does a perfect job with his taunts and sprints in distracting the bosses while Jinhsi nukes them.
My build:
Union level 50
Jinhsi S1. Level 80, talents lvl6, Jue set, double Spectro gmg, Ages of Harvest lvl 80
Aalto S6. Level 70, talents lvl6, Siera Gale set with monkey, ER and Aero dmg, Static Mist lvl 70
Verina S2. Level 70, talents lvl 4-5, Rejuvination Glow set, Bell with healing, all ATK, Variation lvl 70
