open processing sound effects?

Hello everyone,

I got an assignment to code something and add sound.

So far we used open processing & p5.js for coding, I made a simple clicking game and I would like to add sound to it (i want to have sound when it clicks and sound at the end/start of the game).

But I can's figure out how to add it in either one of them :(

Is there anyone who could help me out on this?
