How to upload program in samd21 on robotdyn arduino m0 board?

Question

Arduino

I purchased an arduino m0 board from robotdyn with samd21g18 on board. The board does not have an edbg chip, and I do not have a programmer like atmel ice. I tried to program through the arduino IDE and it didn't work. Bossa cannot open the device. I tried to change the script from samd21j18 explayned pro, but samba hangs when trying to determine the chip id. Basically stuck. I would be glad to hear any suggestions.

What's the fee? The first one that I found from them has an SWD connector, try to catch on to it.
