Automate Microsoft Team creation with Power Automate

Hi guys,

In my tenant I have automated a Team creation from a form with Power Automate. 
See these video: https://youtu.be/YyHa6XW3gBM 

Works fine, but....
This creates a new standard Team.
And actually you want to check if there is a Team already in use and even beter: You want the user lets chose a (custom) template.
Who can help me?

Kind regards
