Minor issue with setting up OAuth2Session

When creating a session via OAuth in appwrite, we can pass 3 parameters - the OAuth provider, success url and the error url.

When no urls are passed, it just redirected to this endpoint: https://cloud.appwrite.io/console/auth/oauth2/success?project=672e4a9d002a1304....

So i passed the success url as /dashboard since thats where i wanted it to go, but it required a complete url.

But that would require me to hardcode that value, although i want the logic to work regardless i am working on localhost, production, or preview-urls

For now i got the logic working via an environment variable, but is there a better way to perform this operation?
