The chat widget — What is public, and what is not
Nominating a table publishes part of it. The widget's snippet sits on your public website, so anything the widget can read can be read by anyone who opens the chat.
That is why publishing is opt-in per row rather than per table. You choose a field — usually a tickbox called Published — and the value that means published. Only rows matching it are ever offered, and only through the two fields you mapped: the question and the answer. Nothing else on the row travels, not the record's id, not your other columns, not how many rows the table has. A draft stays a draft, and a private table cannot be nominated at all.
