As Microsoft Teams becomes more popular and used for collaboration it is likely you will be a guest on one or more teams.  While this works, it can be a slow process of switching between guest networks. And if you want to be on multiple networks at once forget it... You can vote on the idea here  to improve this.  It is on the backlog, but maybe a few more votes can move it to "in progress"!

In the mean time, fellow Teams MVP Tom Arbuthnot created a cool PowerShell that will create you a Chrome App shortcut for each network.  You can find details and links to the PowerShell script here
