How can the telegram bot receive the file_file of the downloaded file?

In the telegram API documentation, I see: "You can pass file_id as a String to resend a photo that is already on Telegram servers," but I can’t find ways to get file_id from the downloaded file. How can i get it?

Depending on the method (file type) that you have chosen to send the file, after sending the file to Telegram, a response is returned. For example, if you send an MP3 file to Telegram using the method sendAudio, Telegram returns an object Audiothat contains the file identifier. Source: https://core.telegram.org/bots/api#audio

It depends on your content_types, for example:

Video:

message.video.file_id

Audio:

message.audio.file_id

Photo:

message.photo[2].file_id
