Abort Siri dictated text message

Hi,

My HomePod misheard me and dictated a text message to someone. I stupidly answered the question “what do you want to say?”with “nothing”, to which Siri replied something like “The message contains ‘nothing’, should I send it?”. I replied no, but how to I delete the draft?

I know there is a draft, because it is not the first time this has happened. The last time I replied “no”, then attempted to dictate a new message. When I asked Siri to send the new message she sent the one I tried to abort earlier instead of asking what I wanted to say.

I have tried simple commands like “abort” and “delete”, but they don’t work. Any ideas?

thank you!
