I'm really confused with https://supertokens.com/docs/community/other-frameworks; is there end to end example. I'm not following on;

If your backend framework is not supported by SuperTokens, you will need to run a separate server with the SuperTokens backend SDK configured. This could be a service in NodeJS, Python or Golang.

is there an example - that I can copy/paste and see i working within a day?
