How to invoke an action in the current router from the child component in Ember Octane?

I am working with Ember Octane version, I want to invoke an action in the 'router' from the child component. The pseudo code is as follows.

**Router**
export default class SomeRouter extends Route {    
    model() {
        return data;        
    }
    @action
    refreshRoute() {
        this.refresh();
    }
}

**SomerRouter.hbs** 

<ChildComponent> //Using child component here

**ChildComponent**
export default class ChildComponent extends Component { 
    @action
    revert() {
       //How do I invoke the "refreshRoute" on the SomeRouter from here?
    }
}

In the revert method of the above child component, "this" refers to the component itself but in the previous version of the ember "this" refers to the router where I could simply call this.refresh(). So how do I achieve this in Ember Octane. Would really appreciate any help.
