Library... Where to find simulink controlled potentiometer?

I'm looking for a resistance that I can control through an input signal, I understand that it is in the junctions section , but I can not really find it.

Thanks!(If you know any other way to control a resistance tell me)

In Simscape Electrical there is a Potentiometer block that models a potentiometer controlled by physical signal:

There is also a variable resistor:
