import { Context } from "https://deno.land/x/grammy@v1.11.1/mod.ts";
Context-aware alias for api.sendChatAction. Use this method when you need to tell the user that something is happening on the bot's side. The status is set for 5 seconds or less (when a message arrives from your bot, Telegram clients clear its typing status). Returns True on success.
Example: The ImageBot needs some time to process a request and upload the image. Instead of sending a text message along the lines of “Retrieving image, please wait…”, the bot may use sendChatAction with action = upload_photo. The user will see a “sending photo” status for the bot.
We only recommend using this method when a response from the bot will take a noticeable amount of time to arrive.
