Determine the type of return based on the provided parameter

Can someone please assist me in understanding how to pass the typeof XXX to a method parameter and specify that the return type should be an instance of that method?

Here is the method I am working with:

public getComponent<T>(component: typeof Behavior): Parameters<(c: T) => T> {}

This is how I am trying to use it:

class Main { 
  getComponent() {
    // Finds an instance and returns it
  } 
}

class Behavior {}
class Item extends Behavior {}


let result = (new Main()).getComponent(Item)

In my TypeScript code, the variable result ends up being an instance of Behavior instead of Item. Could someone please guide me on the correct approach to ensure that the result is an instance of Item?
