Best application to control multiple HUE bridges via Alexa

Heya, I feel lost, incredibly lost actually. Just want to make sure i chase the right rabbit.

Ive been trying various solutions to control my entire home’s lighting via Alexa but given up and just run half on my phone. I would like to be able to say “Alexa, turn on/off all lights” and actually have her control all 100+ lights at once.

Which application do i need? Ive already installed Hassio now im looking for a good guide to follow to get this configured properly.

Very thankful for answers.
