There are many different types of message that a bot can send. Fortunately, methods for sending such messages are similar. Take a look at these examples:
Sending text message
await bot.SendMessage(chatId, "Hello, World!");
Sending sticker message
await bot.SendSticker(chatId, "https://telegrambots.github.io/book/docs/sticker-dali.webp");
Sending video message
await bot.SendVideo(chatId, "https://telegrambots.github.io/book/docs/video-hawk.mp4");
