Create a Team From Existing SharePoint Online Modern Team Site Using PowerShell

How to create a team in Microsoft Teams from an existing SharePoint Online modern team site (connected to Office 365 group) using PowerShell.

 

I have created a modern team site (connected to an Office 365 group) and created multiple document libraries and lists in the site. I want to create a Team in Microsoft Teams using this site so that files will be shared in this SharePoint site instead of creating a new site and also, I can have the same site structure (document libraries, lists etc.) which was already created.
