Complete beginner in trouble with skybox

Hey Community ^^

I only recently started using blueprints and implementing my own assets.
So I created a DDS skybox and created a material for it :

Then I attached that in a blueprint to a movable sphere:

But in this instance the skybox is an abbysal fog. and I would like to see it turn around it’s Axis during game.
I tried adding a Rotator movement Component. But with my lack of knowledge I have no idea how to link it up correctly to make it work.

Any help would be appreciated.
It does not have to effect lighting.
