Control Alexa to just play music

I have a tablet with some dashboard which I want to be able to control theusic from it.
The only thing I want is to be able to turn off/on the music.
Is there a way you know to send to Alexa commands from hubitat like play music?

What OS are you using? Assuming Android.... Also, what app / service are you trying to use to play the music with? Perhaps worth confirming you are actually initiating the playing of the music on the tablet as well, not just wanting to have the control options available on the tablet / dashboard.
