What is the simplest way to find a slack team ID and a channel ID?
<p>We are trying to setup deep linking into slack, as described here:</p>

<p><a href="https://api.slack.com/docs/deep-linking" rel="noreferrer">https://api.slack.com/docs/deep-linking</a></p>

<p>The document states that to open a specific team, the following URL should be used:</p>

<blockquote>
  <p>slack://open?team={TEAM_ID}</p>
  
  <p>Open Slack and switch teams to the specified team. The provided
  TEAM_ID should be a string, like T12345.</p>
</blockquote>

<p>Furthermore, to open a channel in a team, the following URL should be used:</p>

<blockquote>
  <p>slack://channel?team={TEAM_ID}&amp;id={CHANNEL_ID}</p>
  
  <p>Open the channel specified by the CHANNEL_ID provided in the id field,
  like C024BE91L. You must also specify the team with a TEAM_ID.</p>
</blockquote>

<p>My question is simple. Where can I find out what TEAM_ID I need and what CHANNEL_ID I need? </p>
