Telegram stickers are fun and our bot is about to send its very first sticker. Sticker files should be in WebP format.
This code sends the same sticker twice. First by passing HTTP URL to a WebP sticker file and
second by reusing FileId of the same sticker on Telegram servers.

Try inspecting the sticker1.Sticker property. It is of type [Sticker] and its schema looks similar to a photo.
