How to use world edit in Minecraft Bedrock nintendo Switch

So I wanna change the biome of a paricular part of my world. I've read that the only way to accomplish this is worldedit.

Problem is, my world is on the switch. So is there a way I can download my switch save, load it up in worldedit and bring it back to my switch?

Edit: I've figured it out.Use realms to get the file from switch to pc. Then on pc you can use mcctoolchest to edit biomes
