I have switched to the new Teams client and found some issues with a custom app that I've built. It still works in the old desktop client and the web client.
There doesn't seem to be an obvious way to launch the devtools in the new version, does anyone have any tips or tricks for this?
There is an update in the comments of the New Teams Desktop GA announcement here
To enable engineering tool in New Teams client:
UPDATE Feb 24:
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.
From right click on the system tray, Engineering Tools > Clouds > Commercial > edge://inspect
This will open a new window like so.
From the Pages tab you can open up the various browser frames as necessary
