Philips Hue lamps

I have 4 lamps Philiphs Hue, I think bluetooth, I do not have any Philips bridge, these lamps are connected to Echo plus by means of which I can switch on/off and dimmer them.
I tried to connect to Aetoec V3 ST Hub, I could do that, but I simply see the devices as “associated” I could not do anything with them, I just see “associated device”.
What’s wrong?
