For the map, we use Miro, a web-based whiteboard app for our maps that are then displayed in your video conferencing tool of choice (like zoom).
We have had some questions about what browsers Miro supports. The main features of Miro are supported in all the main, up to date, browsers (Chrome, Firefox, Safari). There appear to be a few minor features that are not supported by some other browsers. Thankfully immPACC does not really use these.
Here is the official list from Miro if you want to check or need to share with your IT department.
