Attach an object to player character on runtime

So i have a player character ( a girl) In the game map ive for example a dron. At the beginning the player doesnt have the dron. I want that when the girl finds the dron, for example ontriggerenter ( dron box collider)....that the dron would be "attached" to the player, lets say at 10 in y axis and -1 in z ( some behind and high). This would enable an "aerial camera".... so i need this drone would follow all the movements of the player character ( if i move forward, left, right ...etc in the game Thanks
