Where do I go after obtaining the Phantom Cloak?

I just obtained the Phantom Cloak after defeating the first boss in Metroid Dread, but I can't figure out where I'm supposed to go next. I can pass through sensor doors now, which has led me to an elevator to Catarsis, but that path seems to be surrounded by lava. Every other path I can think of on the map seems to be a Morph Ball passage too, which I don't have access to yet. Where do I go after obtaining the Phantom Cloak?

Illusory wall ahead

As you exit the elevator in Catarsis, shoot the wall to your left instead of going through the obvious looking door on your right. The door goes to lava, the wall goes towards the next E.M.M.I. zone.
