Set alarm and turn off lights

Moving from Google Assistant to Alexa ecosystem. On the GA, I could say, “Google, good night.” Upon doing so, GA would ask me what time I wanted to set the alarm, I would respond and the a HA scene (synced through HA cloud) would to turn off all lights. I would like to do the same and cannot seem to find the correct way to accomplish for Alexa. With GA everything was built into GA, but Alexa does not seem to have that ability, so I’m trying to do through HA but cannot seem to figure out the best way to accomplish. Any suggestions?

With Alexa routines you can trigger scenes.
