You don't want to add the DME to the beer, you want to add the beer to the DME.
If you boil the DME in a small amount of water, you can pour that into the bottling bucket, and then rack the beer on top of it, possibly stirring very gently. This will mix the DME into the beer and give you even carbonation.
If you add the DME to the beer, you will have to do a lot of stirring to mix it evenly, and unless you are very careful, stirring can cause oxidation.
If you don't have a bottling bucket, and you're thinking of adding the DME into the fermenter, then the stirring you will have to do to mix the DME with the beer will completely undo the good work of the cold crash.
Mixing a small hot sugar solution with the beer won't cause any significant problems, as the larger volume of the beer will rapidly reduce the temperature.
