Unreal Engine MarketPlace is exclusive or not?

Hi i am new to Unreal Engine, actually i am an 3D artist come game developer. I was developing an model and also publish that model in 3docean. Now i plan to publish that same model in Unreal Engine MarketPlace. Now i have a big question, can i publish the same model in Unreal Engine MarketPlace? i mean Unreal Engine MarketPlace is Exclusive or Non-Exclusive?
