Opening the Grand Exchange window

How do you open the grand exchange window?

I was original using .openGE(); but now that I'm using the default API I can't figure out how to open it!

 

 public void sellItem() throws InterruptedException

    {

    //Open GE

    OPEN GE WINDOW

    sleep(random(500,900));

    grandExchange.sellItem(256, 539, 224);    

sleep(random(5000,6000));

grandExchange.confirm();

NPC clerk = getNpcs.closest("Grand Exchange Clerk");
if (clerk!=null) {

clerk.interact("Exchange")

}

Updating the post, this worked for me.

// Open a Grand Exchange window
NPC clerk = getNpcs().closest("Grand Exchange Clerk");
if (clerk!=null) {
    clerk.interact("Exchange");
}
