How would I change a MeshPart MeshId in a script?

I’m trying to do AssetService:CreateMeshPartAsync() but I cant figure it out because Im doing it completely wrong and I cant find anything good online. Uhhh Help idk what to do

it is used like this just change the meshidhere

local meshPart = game.AssetService:CreateMeshPartAsync(Content.fromAssetId(meshidhere))
meshPart.Name = 'TestMeshPart'
meshPart.Parent = workspace

the hub documentation needs to be updated
