Send files to telegram

RouterOS Scripting

Hi everyone.
I try to send file in telegram chat, but get: “failure: closing connection: <400 Bad Request>”

{ :local photo [/file find name="123.png"];
/tool fetch http-method=post url="https://api.telegram.org/botXXXXXXXX:XXXXXXXXXXXXXXXXXXXXXXXXX/sendDocument\?chat_id=XXXXXXXXX&document=$photo";
}

When I send message, it works.

/tool fetch url="https://api.telegram.org/botXXXXXXXX:XXXXXXXXXXXXXXXXXXXXXXXXX/sendmessage\?chat_id=XXXXXXXXX&text=test"

The default content-type is: content-type = application / x-www-form-urlencoded and can not be changed.
Unfortunately, we can send files only this way

/tool fetch url="https://api.telegram.org/botXXXXXXXX:XXXXXXXXXXXXXXXXXXXXXXXXX/sendDocument\?chat_id=XXXXXXXXX" http-method=post  http-data="document=http://test.ru/test.jpg" keep-result=no;
