Hi,
Sorry for late reply
I send you the tutorial to join managed Edge Device Drivers: Preview | SmartThings-managed Edge Device Drivers
After joining edge drivers program you should enroll the edge drivers that you pretend.
For example: (NEW RELEASE) Version 5 of the Edge Beta Driver: Zigbee Switch Mc
or
[ST Edge/Beta] Buttons and remotes Edge Driver (Aqara,IKEA,Tuya)
Finally, you must add the device again to smartthings and it will associate one of the edge drivers that you enrolled.
Inside the device you can change the driver if you have more than 1 that have compatibility with your device.
Please, keep in touch if you need any more help.
