[1.15.2] How do I add a new structure to village?

Hello

I'm trying to add a new structure to a desert village, but I don't know how.

I try it through generation over JigsawManager.REGISTRY 

JigsawManager.REGISTRY.register(new JigsawPattern(new ResourceLocation("village/desert/houses"), new ResourceLocation("empty"), ImmutableList.of(new Pair<>(new SingleJigsawPiece("village/desert/houses/teststruktura"), 1)), JigsawPattern.PlacementBehaviour.RIGID));

But I don't think that's a good way.
