How to access the Skeletal Mesh from the Blueprint

I learn with tutorials and am still very new in C++.

I created a C++ class “Character”.
Based on this created a blueprint.
In the blueprint I chose a skeletal mesh.

Now I want to spawn an emitter in the C++ editor with
,UGameplayStatics::SpawnEmitterAttached(…);’’

My problem is how to access the SkeletalMesh selected in the blueprint. The emitter should be attached to it.

thx
