Soundbar hw-q990d not working with any of the voice assistant

I’m trying to connect my new soundbar with a voice assistant.
Connected Bixby, Alexa and Google to smartthings, looks to be working and Recognizing the soundbar, but I don’t see any of them on the menu of the soundbar in smartthings.
Any idea what could be the problem?

As far as I know… voice assistants will only show in Menu > Settings > Linked Services. You only have the ability to refresh the integration or remove it.

Note: I am not familiar with Samsung Soundbars and what features are available to them through the app.
