Can I add a buyer to the discussion? How do I invite a buyer to participate?

Yes, but you can only add buyers who are already connected (the other party has accepted your invitation and their status is "Accepted"): 1. Open the discussion and click [Add Participants] in the right information panel. 2. Go to the [Buyer] tab, select the company first, then select the contact person from that company. 3. After adding, the buyer can see all messages in this thread, including those sent before they joined. You can also click [Discussion] on a document details page to communicate directly with the buyer about that specific document. - The creator cannot be removed; other participants can be removed and will no longer see subsequent messages. - Mentions with @ will be highlighted but will not send separate notifications to the other party. - When the other party views on mobile, formatting like bold text and colors will display as raw symbols. Use text to clarify important points. For buyers not yet connected, go to [Buyer Management] to send an invitation first.
