Problems with Osram GU 10 white dimmable

Hello,

i want to connect my osram gu10 white dimmable with the osram zigbee app - they are listed in the app and i set them to factory and want to connect them but the app said it is not one of this devices and it will be added as standard zigbee device

The problem is as a standard zigbee device i cannot dimm the lights

Is there a workaround or something else?
