[Blind-sysadmins] Microsoft Teams help

Hi, Moving from Slack to Teams. Am getting on with the interface but wondered if anyone else was using it? I am members of a few different teams and I am struggling to work out what I need to read or not at the start of the day, i.e, unread messages. Also I am not sure exactly what is going on in the left hand pane where I can switch between teams and direct messages. Any idea of the best way of doing this? Thanks. Andrew.
