Stuck on the 'Last Wish' Raid: Any Glaringly Obvious Strategy I'm Missing for Riven?

My fireteam and I have been attempting the Riven encounter in Destiny 2's Last Wish raid for hours now, and we just can't seem to get the damage phases right or survive long enough. We've watched guides, but it feels like there's a critical piece of team coordination or a meta weapon choice we're totally overlooking. What's the community's go-to strategy that makes this fight click?
