GU5,3 Smart bulbs

Guys I am looking for some smart bulbs for GU5,3 fittings. Preferable RGB.
My preference would we a Zigbee network and no wifi or bluetooth.

I found Osram makes a model like this for zigbee but I cant find this model in the list of devices to add.
Do you guys know a way to that i can still use this bulbs? Kind regards.

i searched and found this model on Amazon: OSRAM 5,3 Zigbee

You could test if it works with the default Zigbee implementation of Homey.
If that works you could interview the device and report to the developer to implement it in the app.
