How do I change what way a block is facing when using //set [Minecraft 1.16.3 WorldEdit]

I have always used either WorldEdit on 1.8.9 or a less well known version of WorldEdit where I could just do //set 17:2 but when I try to do //set dark_oak_log:2 It says Invalid value for ('dark_oak_log:2' was not recognized) acceptable values are any pattern

I don’t have much experience with newer versions of WorldEdit.

I am on Minecraft Version 1.16.3. and WorldEdit version 7.2.0.
