Help with block rotation

So, uh, I'm a begginer at MCreator, learning step by step and slowly to understand everything. But I'm trying to make a block that just face the player when it's placed, like a mob head. Just that, Y-axis with 8 directions: horizontal and diagonal. But I don't understand very well how to do it, I saw other topics with similar problems but I didn't find the answer I'm looking for. I'm using MCreator 2023.1.
