Can't create 'EditableMesh'

Hello,

why can’t I create a ‘EditableMesh’ from my own asset? The universe is mine and the mesh also belongs to me, so how come it still says that I don’t have permission to use the mesh? This is really frustrating and nothing has worked a tiny bit so far and I’m out of ideas as to why this happens. Is this a ROBLOX bug or is the error caused by me?

local assetService = game:GetService("AssetService")
local mesh = assetService:CreateEditableMeshAsync(Content.fromUri("rbxassetid://105739130909234"))

print(mesh)

just make a meshpart and put the asset id on it.

I know how to make a MeshPart but I wan’t an ‘EditableMesh’ they’re not the same thing.
