Hickman's X-Men and X of swords

Hi! Just a quick question about Hickman's X-Men and how X of swords relates I was planning on reading house of x/powers of X and then the two reign of x trades that collect his run, but they don't collect the issues involved in X of swords as it's a crossover. Do I need to read this or can I skip it? I only ask because it's massively out of print Thank you
