So we used the tool App Studio to implement the “report incidents” React app with teams!
Now you can install the app in Teams and report incidents straight from the teams app. Now the audience can easily report incidents without having to navigate to the website (or install it as a pwa, by all means). Would be awesome to actually have the possibility to officially release it, but given that MS uses about a month to approve the app, this was the best option to move forward!
