Could you reproduce this in MS Teams on the web? Also, what makes you think that this is an issue in NVDA?

[HarishTerala]

Same is reproducible on Chrome.

This issue does not reproduce on Win32+JAWS, Chrome+JAWS, Mac+VoiceOver.

This is not gonna work unless you also give the grid a role="document" or so. Giving a role="document" additionally to role="application" tells the screen reader to interpret the desktop like content of role="application" as a web document. After that NVDA can handle the grid in browse mode as well.
See also this treat for more info:

However, in case JAWS and other screen readers can build the virtual document without the need of role="document", then it should be discussed if NVDA needs to adapt to that behavior or not.

@HarishTerala are you still having this issue with NVDA 2024.4 and the new MS Teams, or while using the browsers last version?
