choose a corner notifications are docked to so this doesn't impact typing of message

In the Webex Teams app, the notification for an upcoming meeting is docked over the text box you use to type a message (bottom right). This blocks a messages I'm typing and since it is docked, I usually dismiss the alert to get it out of the way vs. just moving it out of the way. I'd love the ability to undock this, or choose a corner notifications are docked to so this doesn't impact typing of messages.
