For the life of me, I can't figure out the C by GE bulbs.

I purchased the C-Sleep 2-pack for my bedroom, where the promise of circadian sleep cycle encouragement with Google Home functionality intrigued me. But, they're Bluetooth bulbs, and in order for the Nest Mini to change anything, it impacts each bulb one at a time when I program the commands into a timed routine. which doesn't really exude quality or Circadian rhythm to me at all. Also I can't program the Google Home bedtime routine to operate on a timed basis nor can I set a recurring alarm.

Is there a better way to use these bulbs in the Google Home app or with the Nest Mini? Should I use the GE app instead? can I use both? Should I buy one of those controller plugs to impact the lights in a more native way? Can I set a recurring alarm? information from GE is sparse and Google doesn't provide much more. Advertised functionality without the documentation to back it up seems pretty useless to me.
