Hi i have a problem with the OAuth2 auth

I'm using Flutter and creating a Windows app and I'm having a problem with an error whose nature I don't understand and can't quite figure out if it's actually related to appwrite's OAuth2 authentication or a problem arising from the fact that I'm developing a Windows app

So my question to start with is: is OAuth2 available for Windows? because I can't find anything online

The error:

did you use what was specified for the success url?

I think I have missed some steps at this point now I am sending the relevant part of the code and the configuration

You did not pass the success URL:

account.createOAuth2Session(provider: provider);

Do I have to pass the paremeter even if I do not have a web app but only a desktop one?
