handling shelf interactions

[hollow pulsar]

how can i handle the playerInteractWithBlock event when interacting with the new shelves? i mean, I would like to know which of the 3 sections I am interacting with. I thought about using the faceLocation property but idk if there's an easier/simpler way of doing it

I don't think there's a way yet, I tried using block inventory but apparently shelves don't store their items in a inventory

there's a tool called precise interaction that allows you to get the exact block face location that you clicked, you could use that and map out all 3 itemslots
