We are getting closer, and are still working thru some bugs, but hope to release this as part of a Public Preview pack in early 2021! (Windows 10 released with the December 2020 pack this week)
You can learn more about the new Microsoft Teams Public Preview program here: https://aka.ms/TeamsPublicPreview, and Teams administrators can find documentation to manage which users will see the Public Preview option here: https://aka.ms/TeamsPublicPreviewAdmin

Really looking forward to this being implemented. The side of my screen is becoming unruly and it just appears to be in poor choice to use a custom notification mechanism when there's one already in place and available within the OS.
