Bot API message endpoint does not return message_id

When a bot posts a message via POST /ocs/v2.php/apps/spreed/api/v1/bot/{token}/message,
the response appears to always be DataResponse(null) with HTTP 201.

As far as I can tell, the message is created internally
($comment = $this->chatManager->sendMessage(...) in BotController.php, line ~160),
but the comment data is not serialised into the response.

This means there seems to be no way for the caller to obtain the message_id of the posted
message. Without it, building reply-chains or dialog bindings is not straightforward —
as a workaround, the bot has to scan incoming webhook payloads for its own text.

It would be great if the response included at least { "id": <message_id> }, analogous
to the chat message API.

Relevant code: lib/Controller/BotController.php, line ~184:
return new DataResponse(null, Http::STATUS_CREATED);

Talk version: 23.0.3

Start in lib/Controller/BotController.php around the sendMessage call near line 160 and the DataResponse return near line 184. Trace how the created comment is represented and compare the response with the chat message API. Done means POST /ocs/v2.php/apps/spreed/api/v1/bot/{token}/message returns the created message_id instead of null.
