I have been trying to make this work for a while and cant seem to get it :( Maybe someone can help.
asset = 1117577896 -- I need this so I can insert my model after I started the game
model = game:GetService("InsertService"):LoadAsset(asset)
model.Parent = game.Workspace
model:MakeJoints()
model.Name = "InsertedModel"..asset
There is my previous code.. I don't know what to do.

I am pretty sure there is, if you can insert a mesh from F3X tools, there has to be a way. Just lots dont know ;-;
Do you own the model? If you don’t and it’s not owned by Roblox, it won’t let you put the model into the game.
It will I did it earlier this month but the item got removed
You can use InsertService to insert models, however, you have to own that model you insert and be the owner of the place you put the script it.
