As the title says, I can't seem to remove biomes from world generation successfully. I'm attempting to remove a modded biome from my world generation, but I'm not exactly versed in BiomeTweaker. It's been somewhat complicated for me to get the gist of this mod. I've been at it for a while, but I can't seem to remove this biome from the world generation. The script I'm using goes as follows:

mangrove = forBiomes("wildbackport:mangrove_swamp")
mangrove.remove()

My apologies if I'm simply not understanding something, but I haven't been able to find a solution for this so far. I have the script in the right folder, but the biome is still able to generate in the world. Any help would be greatly appreciated.
