Set payload to empty string.

I realise that, but maybe the payload is needed further in the flow. In any event shouldn't there be an optional name property, like other UI nodes, so we could enter text instead of showing the payload, so for example we could enter " Please confirm action" (and yes I know I could inject that text as a payload )

Yep. This is a prime candidate for a typed input to permit either string or msg. IMO but then I feel that way about ALL nodes (I hate having to put change nodes everywhere!). There is an open issue somewhere on dashboard about permitting user choice when it comes to where the payload comes from but I am told there are difficulties implementing this on dashboard.
