Create — or get — the order's general comment thread for one visibility tier.

Note: This API requires additional fund configuration to be enabled. Please contact us if you would like to try it out.

Right now each order can have at most one general thread per visibility tier: if the thread already exists its threadId is returned unchanged with created = false; otherwise an empty thread is created and returned with created = true. The response is always HTTP 200 — branch on created, never on the status line. The newly created thread stays invisible to thread listings until its first comment is imported (see ImportComments).

visibility is shared (investor-visible) or internal (GP-side only). By default your API key's service account can create both shared and internal threads.
