changing level when colliding with an object

hi! i am new to unreal engine and to game development. I am an artist and designer and i want to create my first game. Programming is not usual for me. But that will not stop me. I want to learn how to program the game by my own.
I hope that with this Thread i can learn some tips to reach my goal.
i want to use blueprints. What i want to ask is how to change between levels when the players collide with an object??

here there is an example. I want to change to an another level when the cube collide with the black part of the door.

Thanks for reading!
