How to set members of a component?

I’m trying to make a third person game where moving the mouse wheel changes the camera distance. Essentially what’s dicussed in this thread, but with a different input. I don’t understand how to create a “set” node like in the examples (the top right of the screenshots, the one with a target and value input. When I create set variable nodes, they only work on BP-level variables, not component member variables like SpringArm::TargetArmLength.

How do I actually get/set these?

You need to drag the component reference to the graph, then drag from the pin in that variable and search for Set Target Arm Length.
