What are DC Comics collected editions/stories of Dark Multiverse/D.N.: Metal in order of prequel, prologue, continuation, aftermath, etc...?

Alrighty let's see. There aren't direct prequels, but the Metal series has been said to be a continuation of Scott Snyder's Batman run, which included the Batman Black Mirror graphic novel, the 50+ issue Batman (2011) series which is collected in 10 tpb vols, and then the 14 issue All-Star Batman (2016) series. Then Dark Knights Metal is collected in 4 graphic novels which are listed on Wikipedia. After that, Scott Syder launched Justice League (2018) and wrote 5 tpb vols, and during those you also read the batman who laughs tpb and then the batman/superman (2019) vol 1 tpb, and you could also optionally check out Batman Last Knight on Earth, which is a dark future story taking place after justice league. And all this stuff leads into Dark Knights Heavy Metal which just came out. As for tales of the dark multiverse, well that series is basically, each issue is an alternate universe version of a classic dc story. So one issue shows what happened if the heroes didn't survive the blackest night, one issue shows a dark alternate universe for the death of superman story, etc.
