Fortnite Kugler boost?

I play fortnite and I wonder how to give the Kugler boost on the PC

Go into the settings and bind z. B. Your space bar for boost with Kugler

Here is a guide:

Go to the pause menu
Click on the gear
Click on the Button assignment tab
Scroll down to the point "ball"
Documents boost with one key (for example, space bar or Q or F)
