If you have dangerous buttons in a flow, it is sometimes nice to have a safety switch to stop them being accidentally pressed.
I have posted flows in the library in the past which do this but in a more complicated way.
This is really easy, simple and not anywhere as difficult to apply as the previous efforts.
It also has the advantage that it is virtually limitless to how many buttons it can do.
It doesn't get more difficult as you get more buttons.
Hope you enjoy it and find it useful.
Instructions are included in the flow - the Read me please node.
