Floating Islands (Without Center Island)

I'm trying to create a custom dimension in 1.19.2 and I'm using the code generated by MCreator for reference. I want this dimension to be sky islands, but the closest option I see is "end-like" (this generates a center island surrounded by void, which I don't want). I'm guessing that the following section is responsible for making the dimension resemble the end in shape (more specifically the last line):
        "barrier": 0,
        "fluid_level_floodedness": 0,
        "fluid_level_spread": 0,
        "lava": 0,
        "temperature": 0,
        "vegetation": 0,
        "continents": 0,
        "erosion": {
          "type": "minecraft:cache_2d",
          "argument": {
            "type": "minecraft:end_islands"```
Is there a value that I can change `"type":` to in order to make the dimension generate as floating islands instead of as the end?
