Would picking up the glaive disarmed from the opponent be a standard action? Or would it be a bonus action?

Usually I'm not to specific on picking up or equipping a weapon during turn orders. But I would say to pick up one thing is like a free action or part of movement as it can usually be a very simple thing to do. If anything, I would also imagine kicking it a short distance to be bit of movement action which would just cost a bit of movement to give it that bit of distance.
