It is up to Integration developer to support the scenes (with state and attributes).

Note for developers here: Supporting Scenes | Home Assistant Developer Docs

Hello
With what you tell me, do I have to understand that it is not possible? Alexa media player does not support scenes?

Nope, apparently not, you can engage with custom component owner to support it.

Edit: double checked the integration and it doesn’t support it.
