Can't detect/expose ColorLighting Tags to Alexa

I have a Yeelight v1 color bulb which I want to expose the Color item of the color channel to alexa.

But it can’t be detected with alexa …
Switchable and Lightning works perfect but ColorLighting tags won’t get detected somehow
.config looks like this:

Does someone have a clue? or is it just not supported?`
Thanks to all and regards

entering http://192.168.178.XX:8080/api/testuser/lights?debug=true gives me this error:

[{"error":{"address":"/testuser/lights","description":"Not Authorized","type":1}}]

How can I authorize?
I really would need help here since the documentation isn’t really detailed and I don’t know where to start
