Did Blink successfully upload? The mayfly can only handle one sketch at a time. The fact that your board is flashing in the ways you describe means that it is probably not fried.
As far as I can detect, you have not yet connected to your board. The serial monitor would be a way to connect to any board and see what’s on it. There are lots of charging cables that do not convey data, so that could be an issue. Now that you have learned about the serial port, try a few different cables again to see if that’s the issue.
You also need to have the Mayfly driver. In the Arduino IDE under Tools>Boards Manager, you need to confirm that the Mayfly is selected. (https://www.envirodiy.org/mayfly/software/)
