File to send. Pass a fileId to send a file that exists on the Telegram servers (recommended), pass an HTTP URL for Telegram to get a file from the Internet, or pass "attach://<file_attach_name>" to upload a new one using multipart/form-data under <file_attach_name> name.

A thumbnail's width and height should not exceed 320. Ignored if the file is not uploaded using multipart/form-data.
