title: Discord.py: How to go through channel history and search for a specific message?
body: <p>Essentially, I want the bot to go through the channel's message history, find a message containing some particular text, and then give out the link to the message in the same channel.</p>
  <p>Going through the documentation, I imagine I will make use of <code>async for message in channel.history(params)</code> but I cannot figure out how for my particular use case.</p>
