Setup: MX Master and MX Keys.

I had Logi Options installed when it prompted me to try the beta of Plus. It was unclear to me whether I have to uninstall Logi Options to use the Plus beta. I installed them side-by-side. On the first launch of Plus, I saw that only MX Keys is supported and MX Master is not. So I was tempted to uninstall Plus again, because I was under the impression that I cannot manage my MX Master anymore. However, when I opened Logi Options back up, it was able to manage MX Master and had a reference to take me to Plus for MX Keys.
