<p>To enable engineering tool in New Teams client:</p>
<ul>
<li>
<p>Create a configuration.json file under: %localappdata%\Packages\MSTeams_8wekyb3d8bbwe\LocalCache\Microsoft\MSTeams</p>
</li>
<li>
<p>In the file add: {“core/devMenuEnabled”: true}</p>
</li>
<li>
<p>Restart the client.</p>
</li>
<li>
<p>Right click the Teams client icon in system tray to see the Engineering Tools entry point.</p>
</li>
</ul>
<p><strong>UPDATE Feb 24:</strong></p>
<p>It is now a little trickier to get to individual instances of the Edge dev tools. With the current version 24004.1307.2669.7070 this works for me.</p>
<p>From right click on the system tray, Engineering Tools > Clouds > Commercial > edge://inspect</p>

<p>This will open a new window like so.</p>
