title: How to find the forUsername parameter for a specific channel
body: <p>I'm new to working with the YouTube API v3, and StacOverflow in general, so sorry for any mistakes.</p>
  <p>Right now I am having trouble understanding the <code>forUsername</code> parameter. For some channels, such as <em>YouTube</em> or <em>H2ODelerious</em>, I am able to find the correct channel. When it comes to using channels such as <em>leagueoflegends</em> or <em>playoverwatch</em> (both of these being the names of the channels when it comes to composing a URL of form <code>https://www.youtube.com/c/...</code>) I do not find the correct channel and neither find no channel at all, nor one with no views or subscribers.</p>
  <p>Here is my code:</p>
  <pre><code>channelStats = testConnection.channels().list(
      part ='statistics',
      forUsername ='Youtube'
  )
  response = channelStats.execute()
  </code></pre>
  <p>If anyone knows whether there is another way to properly identify the correct channel while using the <code>Channels.list</code> method, please let me know. (Am using YouTube Data API v3 through Google's Client Library for Python and Python 3.8.)</p>
