Hi,
I created a lightning component that I embed in Community Builder custom page.
I called a apex controller function that will redirect to the Community Builder Home Page

This is my apex method
@AuraEnabled
    public static pageReference redirectToHomePage() {
        pageReference objHomePage = new PageReference('/');        
        return objHomePage;
    }

I'm not sure exactly how to call the Community Builder Home Page
I also get an error 'Return type does not support AuraEnabled'

I just want to redirect to Community Builder Home Page
