Platform Movement Object - variable jumping height

[Oreo]

How can I use the PMO object and give my character variable jumping heights? For example, when I quickly press the jump button the character jumps only a small height. But if I hold down the jump button the character makes its full jump height.

Upon pressing space
+ Player is standing on ground
> Jump

Repeat while space is pressed
+ Player is jumping
> Player is holding jump in the air

Thanks! I got it working now.
