Set the jump height

I am new to Unreal Engine but I believe you have to go to:

“Character Blueprint” → “Character Movement (Inherited)” under Components

then under Details there should be a tab called “Character Movement: Jumping/Falling” where you should set the “Jump Z Velocity”

Hi, I am making a game and the player jumps way to high, I need him to jump like half as much. Can someone tell me how to make that happen??
