Teamify and groupify a SharePoint classic site programmatically?

Hello,

I have some questions related Microsoft Teams and Groups. I would like to know if it is possible to link a classic web site to Microsoft Teams and do the normal relation between Groups.

At the moment, I have a test SharePoint Online Tenant and read some posts related with this topic:

I would like to know if there is a way to  perform that operation programmatically. I am not sure how could be done if we can use CSOM, PnP framework on C# or Functions?

Thank you!PD. I am not sure if this is the correct category, but if you need just change it :)
