FileOptions filename and contentType is can't work well

Bug Report

I have read:

• Usage information
• Help information

I am using the latest version of the library.

Expected Behavior

I'm trying to send a Document with a custom file name

Actual Behavior

What happens is that the file name in Telegram becomes the default file URL to be "12345678990.pdf", it should be "file-name.pdf"

Steps to reproduce the Behavior

I have used the function for .sendDocument using FileOptions in this way

const url = 'https://media.com/12345678990.pdf'
const fileOption = {
 filename: "file-name.pdf",
 contentType: "application/pdf",
};

.sendDocument(chatId, url, options, fileOption);

Seems that similiar behaivor is on telegraf by sending from file_id https://github.com/telegraf/telegraf/issues/1062#issuecomment-659553766

Probably filename can be given only when uploading (from Buffer or Stream), so you should try to download the file and then upload it to telegram with your fileOptions
