add wordpress endpoint to account page

Hi peoples
I much prefer the layout of the ultimate members account page over the wordpress my account page but i am wanting to add some tabs to it. I have found the code to do this and thats working without any problems. What I want to do though is display the wordpress endpoint pages ‘orders’ and ‘addresses’ but cant for the life of me figure out what code I need to use. I have just copied the whole orders page code into the new tab code and that worked but there must be a simpler way of doing it. Im no code expert but i know enough to be able to implement any instructions. Surely one line of code which pulls the order.php page or something simple??
