[SOLVED] FabricItemGroup.builder() not recognizing displayName() 1.20.1

[light lantern]

Hi, so I am following this tutorial (https://fabricmc.net/wiki/tutorial:itemgroup?s[]=custom&s[]=item&s[]=group) for making item groups in Fabric on minecraft version 1.20.1

As you can see in the screenshots I provided, the displayName method on the FabricItemGroup.builder() object is not found.

I have been researching this and looking at several different examples online for a couple of hours.

What am I doing wrong here?

is there any information I can provide to make things easier to figure out?

https://docs.fabricmc.net/develop/items/custom-item-groups it's definitely there

what mappings are you using?

https://maven.fabricmc.net/docs/yarn-1.21.3+build.1/net/minecraft/item/ItemGroup.Builder.html#displayName(net.minecraft.text.Text)

in Quilt mappings (what you're probably using, seeing as you're actually using Quilt and not Fabric...) displayName is just name

thanks!
