From my past experience as an STS and then as a clerk , once the new Chromium based Edge (not the orginal Edge) came out, Google Chrome and Microsoft Edge have basically the same underpining, known as Chromium, with some user facing differences. For the ward, I was in at the time, we had both we had both Chrome and Edge (Chromium based) to allow people 2 choices. I have found these 2 brower options is enough otherwise it can get interesting and some people may try to make it like their personal computerm, which can sometimes be interesting.

If you are a STS, you might be able to get some more/better/offical guidence in that regards from the GSD.
