How to launch future in Actix (actor model framework)?

I'd like to send a message and get a String back.
How to launch future in Actix.

let my_response = 
self.driver_address.send(GetDrvConfig {}).await.unwrap().unwrap();    

and wait for a reply?

How to do it?

impl Handler<GetConfig> for DataHub
{
 type Result = Result<String, ()>;

 fn handle(&mut self, msg: GetConfig, _: &mut Self::Context) 
 -> Self::Result
 {
   let res = 
   self.driver_address.send(GetDrvConfig {}).await.unwrap().unwrap();    
   Ok(res)
 }
}

#[derive(Debug, Clone)]
pub struct GetDrvConfig {}

impl Message for GetDrvConfig
{
  type Result = Result<String, ()>;
}

impl Handler<GetDrvConfig> for Driver
{
  type Result = Result<String, ()>;

  fn handle(&mut self, _msg: GetDrvConfig, _: &mut Self::Context) 
  -> Self::Result
  {
    Ok("MY RESPONSE".to_string())
  }
}

Edit:

let send_msg = drv_addr.send(GetDrvConfig {});
let send_to_other = actix::fut::wrap_future::<_, Self>(send_msg);

let _f = send_to_other.map(move |result, actor, _ctx| {
       match result {
                Ok(v) => {
                    // How to return a response?
                    let response = v.unwrap();
                    println!("RES: {}", response);
                },
                Err(_e) => {}
       };
}).wait(ctx);
