Make a projectile recall while pressing a touch

Hi, i’m new to UE and BP and i want to make a projectile that you can recall (like using The Force or gravitate to player) while you Right Click. I made the trhowing system, no problem with that but i don’t know how to make the projectile come back.

I made that:

But i want the velocity to be applied while i’m holding Right Click and not only when i click.
Can you help me with that ?

PS: i’m french so variables are in french, i’ll translate for you: “Arme” is Weapon and “Force de rappel” is recall force.
