2021 New Gledopto Dimmer GL-SD-001 is Unsupported

[ildmgithub]

Hello,
I ordered the new gledopto dimmer GL-SD-001 but it is not supported by zigbee2mqtt. I tried to follow the instructions for adding a new device, but I am stuck. The instruction to add new devices is not clear for me.

Information about the device + link
