How to use a preset in my server's world

[ItDaRaptaYT]

I want to use the Overworld Preset that is a default in Superflat Java. I tried putting the this here into the generator settings into the generator settings type-box: minecraft:bedrock,59*minecraft:stone,3*minecraft:dirt,minecraft:grass_block;minecraft:plains;pillager_outpost,village,biome_1,decoration,stronghold,mineshaft,lake,lava_lake,dungeon

But, it doesn't do anything. Help!

I love minehut

(yes it is known that the generator doesn't work with flatworlds as of now)

Unfortunately I don't think Minehut supports custom superflat worlds, maybe this should be something minehut looks into
