I want to power my STM32WB30 MCU from a coin cell. Can anyone provide me with a circuit of some sort to do so. I am beginner with this and don't have any testing equipment to test the circuit so a circuit or schematic would be really helpful.

Thanks a lot. What is the MOSFET being used? The part number is unclear
