Could they please make Envisaged Echoes easier?!

I swear to god, why are those god damn Envisaged Echoes so hard and annoying? I can't do the new ones for Ayaka and Ayato. What the f*ck are you supposed to do here?! Why are these always so difficult? I remember Yelan's Echo was incredibly hard for no reason. It's just a cosmetic feature, so why are they so challenging to obtain?
