Simple HA button to turn off the soundbar

[Soiski71]

Hi, I thought it would be easy to turn the soundbar easily off by generation a button (card) to do this. But I have not found a way. Only showing it as possibility in the standard card that it created .
.

I have tried on the scripts but if trying to do any actions on the soundbar it does not allow it ?

Any suggestions ?

You can just use a service media_player.turn_off
