How to generate actor after an in-game craft

Hi guys
Here is my blueprint.
This blueprint was made to work as a market place. There is a button that you can press to sell some stones and wood in return of getting a brand new axe. This code is working, at least ressources disappear from the player’s stuff, but I don’t know how to generate the axe. My axe is generated by a “BP_Hache” blueprint (hache because I am french), but what should I add to this blueprint ? I want the axe to drop from the sky and fall to the ground.
Thank you for response
