Smartthings, Echo/Alexa, Harmony, Samsung wifi soundbar playing spotify

Does anyone know if it’s possible to use alexa for voice command(s) to play music from Spotify on a samsung soundbar ( (HW-MS650). I can play spotify using my phone app or desktop spotify program. I can play music from amazon music to the soundbar. I can even play spotify using voice commands with Alexa on the echo device. I can not figure out how to play spotify music using alexa voice commands, with music played on my soundbar.

I’m not sure it’s possible but thought I’d ask incase someone has figured a way to make it work.
Thanks

Depending on which Echo device you have , you can connect the Echo via Bluetooth to the Samsung speaker through the Alexa App. Then, just ask Alexa to play the music from Spotify on your connected speaker.
