Alexa says what it's doing, just do it

[userFcAvtvnQbR]

I'm using Alexa for voice feature with my Samsung Q80T 2020 TV. When i ask it to change the channel, it's repeats it back to me.

How do i get it to just change the channel, without repeating what i said? 

Example:

I say "Alexa, change channel to 200"

Alexa/TV loudly says "tuning to 200"

Don't say it, just do it.

Thanks for the help
