Push - Ask for confirmation

How does one set up flow with push and ask for confirmation? I am able to set up push notifications, but not the part with ask for confirmation.

Put the mobile flowcard in the AND column, instead of the THEN column


Make a push in the AND section.
Use the word ‘confirm’ in the start of the push message.
This will give you a yes/no push.
If you answer Yes, it will complete the flow.
If you answer No it will abort.
