Question: FirmwareUpdater settings for Ender 3 v2

How do I setup the FirmwareUpdater plugin to support the Ender 3 v2 printer?
I assume I need to choose STM32 and stm32flash.
What should all the other settings be? like BOOT/RESET pins?
When I compile using VScode and "Auto Build Marlin" I get bin file. Is this file OK or do I need a different or modified file?
