How to get Bixby to stop conversation

[pizza_pablo]

I've searched here and Google but have only found instructions to disable Bixby.
I just want to know what to say to Bixby to stop a conversation. After reading a text message Bixby gives me 2 choices. Reply or read again.

What do I say to get her to do nothing?

What do I say to get her to do nothing and go back to sleep?

I don't use Bixby but when my Alexa keeps talking I say, "Alexa stop" and that quiets her down.
