STM32WL5MOCH6S battery voltage reading

[Trace_LEMS]

Hi,

We have developed wireless temperature sensor using STM32WL5MOCH6S module , it is fully battery operated device and Battery is connected directly to supply  pin of the module, in this we would want to the read battery voltage , is there any register or command available for reading supply pin to read the battery voltage or any other method to read the battery voltage?

Kindly help us in this matter.
