Does the DF Robot Xbee Shield have a level shifter?

Hi!
I wonder if the DFRobot Xbee Shield (SKU:DFR0015) have a level shifter, so that it is safe to use my Xbee module (XB24-Z7UIT) with my Arduino Uno? My Xbee module has an operating supply voltage of 2.1 - 3.6V, and I have read that it could be damaged if it is connected to the Arduino if a level shifter is not used. I do not have a lot of skills in electronics, so any help would be greatly appreciated!
Kind regards,
