Question

I am using appwrite to generate a url for user authentication (Oauth2).after the redirect url is made and i try to redirect the user to the generated url, i get CORS error in the console.how do i add my server's origin in the auth provider's allowed origins?       if(providerid === "google"){
          authurl = await account.createOAuth2Token(
            OAuthProvider.Google,
            "http://localhost:3000/createSession",
            "http://localhost:3000/unexpected"
          );
        }

if(authurl !== "")
          return NextResponse.redirect(authurl)
        
        return NextResponse.json({
          message: "signup Failed",
          success: false,
          authurl,
        });

This is the CORS Error:Access to XMLHttpRequest at 'https://accounts.google.com/o/oauth2/v2/auth?client_id=64278655-.......' (redirected from 'http://localhost:3000/api/users/signup') from origin 'http://localhost:3000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
