Hi all, What is the true way to send mp3 anonce to my tv? I have homeassistant server with LG TV integration and LG Soundbar, all working fine, but sometime I need to send text-to-speech to this TV. I'm searching for example, something like Postman request to TV. (I'm not searching for implementation with Google or Alexa because homeassistant have internal tts and vtt which working fine and can be used independent without internet ) Thank you for your time! Kind Regards, Jeff
