For some reason the items don't appear in the creative menu.

Steps to reproduce the behavior:

1. Go to 'Search in the creative menu'
2. Search 'Any of the item in the mod'
3. See nothing

Mod Version
v3.2

Mod List [If Applicable]

• Fabric Api for 1.21.5
• Jake's build tools for 1.21.5
  Datapack List [If Applicable]
• None

This is a datapack packaged as a mod, therefore its impossible to add the custom items to the creative menu. Until Minecraft adds a way to do this, there's not much I can do.
