Usually debugging the Teams web app inside chrome is preferable. When this is not possible, due to the issue not being reproduced in the Web Browser, reproduce the issue in the full client and then connect the full client to Chrome, to get debug logs, as shown below.
open PowerShell (or cmd) as an administrator in the directory:
%appdata%\..\Local\Microsoft\Teams\current
if teams currently run, quit the app:
run the command (in cmd drup the '.\'):
.\Teams.exe --remote-debugging-port=31337
(or any other port you want)
open Chrome and go to:
make sure the port is configured properly:
click on the inspect link - that it!
