Where is Set Scalar Parameter Value?

It’s odd. In the documentation page, I can see this image:

https://docs.unrealengine.com/latest/images/Engine/Rendering/Materials/ParameterCollections/MPC_Added_Nodes_To_BP.jpg

Where I see clearly “Level Blueprint” and the “Set Scalar Parameter Value”.

I don’t understand then how to continue with this. Anyway, thanks for your time, Dannington.

Someone have any ideas?.
