Welcome to the community and thanks for posting! Are your Hue devices connected through SmartThings or Hubitat?
With Hubitat, you can control Hue Groups directly.
SmartThings only exposes the individual lights, so if you control multiple individual lights from a rule you might experience a bit of popcorn effect (each light turning on slightly after the next). For controlling Hue groups in SmartThings, most people like to use the Hue B Smart community developed integration.
