Are you discussing the requirements or collecting them? Those are two different tasks. I’d you’re making a formal specification it is critical for vendors and suppliers to have it on paper. This protects both side and may be why at least a slack chat is being asked for. In general collecting requirements needs a formal document or other central source of truth, but for discussion it’s better to do this in a meeting with a focus on updating the document afterwards. This really protects both sides.
