Unable to Create New Entities with Components

I am trying to create a VFX entity that I can spawn in the world, but I keep getting an error that mentions invalid access, though I am following the tutorial on the unreal engine’s YouTube channel.

That tutorial is old, scene graph changed a lot since then…

Now to add a mesh you need to add the mesh component subclass that is on the assets digest file…

Thank you so much. Does it still follow the same syntax?, and also what would this look like for prefabs?
