NewEphemeralMessage

[Alexkurd]

If the bot is a chat administrator, it can send an ephemeral message to any non-bot member of the chat at any time without needing to specify a callback_query_id or reply_parameters.ephemeral_message_id. In this case, the message may be delivered across multiple active client applications of the user, but is regardless not guaranteed to be delivered to any of them.

Direct version
curl -s -X POST "https://api.telegram.org/bot/sendMessage"
-d chat_id=<chat_id>
-d text="New Ephemeral"
-d receiver_user_id=<user_id>

Pushed a small follow-up that reuses NewMessage, documents the admin/non-admin requirements, uses receiverUserID, adds direct-admin serialization coverage, and applies gofmt. This keeps the helper consistent with the existing constructor contract.
