Hand this Meta thread to another tool
POST/api/conversations/:conversationId/thread-control/pass
Passing NAMES A SUCCESSOR — "you take it" — and the default successor is Meta's own inbox for this product: the Instagram Inbox on Instagram, the Page Inbox on Messenger. Sending an Instagram thread to the Page Inbox leaves it somewhere that does not show Instagram DMs at all, which is why the target is resolved from the conversation's source rather than from one constant (38 §A5).
We stop being able to send the moment Meta accepts, and the refreshed
conversation says so: its capabilities carry free_text.allowed: false
with reason handed_over.

The refreshed conversation, whose capabilities say whether this panel may still write.
Not authenticated. code: account_disabled means the member's seat was deactivated in this workspace: the session is over even though the token was not revoked (clients sign out and clean up).
Authenticated but not allowed.
Resource not found (or not visible to the current tenant).
This conversation cannot be handed over (no Page behind the channel, no platform id for the contact), or Meta refused — its own sentence is in detail.
