How can I make a character bounce?

I’m trying to make the player bounce on various objects to reach a key but I don’t know how to get it to work. I’ve tried various scripts but my player refuses to bounce. What’s the simplest way of making a character bounce back up when it lands on something? Does my player need to be a rigidbody?

yes…in the collider… the Material needs to be set to bouncy… then it will bounce…
