Using this PowerShell script you can create new teams with type,
channels, owners and members in Microsoft Teams using csv file.

In the csv file used for team creation, you need to specify the
following.

• New Team Name
• Team type (private or public)
• Channel names seperated by semicolon(;)
• Team Owner seperated by semicolon(;)
• Team Members seperated by semicolon(;)

If you want to create just team with General channel alone, don’t
specify channel names, just leave it as empty.
