How do I insert an R6 dummy into Workspace with a script?

You would have to add the dummy into either replicated storage or server storage (depending on whether the script is local or not) and clone it into the workspace. Hope this helps! :)

You could add a dummy in server storage and add the seguent script

local cloneDummy = game.ServerStorage.Dummy:Clone()
cloneDummy.Parent = game.Workspace
