Regarding the placement of positive and negative poles of battery on the sensor

LPWAN Nodes RAK7204

I have a RAK7204, and I need to replace its battery. I would greatly appreciate it if someone could advise me regarding the placement of positive and negative poles on the sensor i mean how I should place the positive and negative poles on the sensor? which side of sensor the positive pole should be placed?
because it is written: when replacing the battery, it is necessary to strictly confirm whether the positive and negative poles of the connector are correct.

Hello @James

The polarity is printed on the PCB:
GND close to the screw

VBat on the other side

Here with the cable, RED = +, Black = GND
