What abilities triggers Halo's plat?

Just curious on what actually triggers Halo’s plat. ability. I know regular skills that deal direct dmg/DPS triggers it, but what I’m confused with is… from what I was told, Hive’s abilities work with Halo’s plat., but not Hallo’s clones nor Castellan’s turret.

I saw haloways clones trigger the halo plat skill also its weird that dogface his bronze and silver dont trigger it but the gold of nightingale that triggers it
I dont know about all the hero’s but some are really useful but some are just weird that they dont trigger it
