Problem sending SMS with Siri

I can use the "Hey Siri" to wake my watch and tell it to "Tell my wife I am on my way home"; and it will say "Ok, I'll send this: To: wife \nI'm on my way home" follow by a "Don't Send" label which I can press to cancel.

The problem is there is no button that I can confirm to send it, like I would if I did the same with Siri on my iPhone.

Any ideas? TIA
