Make sure that your program was compiled to start at 0x2000 (8k) because the bootloader takes the first 8k. CircuitPython's [https://github.com/adafruit/circuitpython/blob/master/atmel-samd/boards/samd21x18-bootloader.ld linker script] is an example on how to do that. | Making your own UF2 is easy!
