Use this when the user shares a bid their company won, for Tenda to learn from, e.g. after Tenda offers to learn from winning bids. Tenda keeps it in the workspace's Library and learns what worked in it (structure, tone, the evidence it uses) for the bids it drafts. Pass the bid's text as the user shared it, not a link. Needs a Tenda account and workspace. Do not use for the buyer's questions for a new bid (use start_bid_draft or continue_bid_draft).
