3.7 V Li-Po battery and MKRWAN1310

I looked MKRWAN 1310's pinout diagram (https://content.arduino.cc/assets/Pinout-MKRwan1310_latest.pdf) where Li-Po 3.7 V battery is connected to JST S2B-PH-SM4-TB(LF)(SN) type of battery connector.

According to technical specs, the operating voltage of the circuit is 3.3V.

Is it safe to connect 3.7 V Li-Po battery to MKRWAN 1310 as the pinout diagram shows? Isn't there need for an external step-down voltage regulator (from 3.7 V to 3.3V) or is it built-in to MKRWAN 1310?

I got an answer to this question from Arduino's support.

The MKR WAN 1310 has a voltage regulator inbuilt on it, so it's possible to attach the 3.7V battery to the JST connector on the board and the board should be able to work without getting damaged from it.
