Difficulty in registering mod item to ItemGroup (1.21.5)

Description

Heya, I'm really new to modding so please go easy on me! Been following the posted documentation for Fabric modding and I've hit a snag in registering my modded item to an ItemGroup. Here's a snippet from my Mod.java:

public class Culinaria implements ModInitializer {
	public static final String MOD_ID = "culinaria";
	public static final Logger LOGGER = LoggerFactory.getLogger(MOD_ID);
	@Override
	public void onInitialize() {
        LOGGER.info("Hello Fabric world!");
		CulinariaItems.initialize(
				ItemGroupEvents.modifyEntriesEvent(ItemGroups.FOOD_AND_DRINK)
						.register((itemGroup) -> itemGroup.add(CulinariaItems.FISH_SANDWICH));
		);
	}
}

Attempting to build the project gets me a few errors, as follows:

I suspect I've not placed ItemGroupEvents.modifyEntriesEvent in the correct place, but I can't tell. Wiki says to add it to the mod items class initializer method which I have done. I do see that the documentation is intended for 1.21.4, not 1.21.5, but also can't tell whether this is a code error or a 'you're using documentation for the wrong version you idiot' error. Any advice is greatly appreciated! Thank you!

        ItemGroupEvents.modifyEntriesEvent(ItemGroups.FOOD_AND_DRINK)
                .register((itemGroup) -> itemGroup.add(CulinariaItems.FISH_SANDWICH));
    }
