I'd say you're well within your rights to reject it for any reason, but particularly if you WFH you will interface with it a lot. And teams is kind of annoying for those reasons and more, although for me it is a tolerable pain. But you also have to weigh up whether the pros of the role outweigh that con as well, otherwise you might be doing yourself a disservice by focusing on that one issue.
