Yes, thanks for mentioning that 🙌

You are right. We just need the authentication magic link and its returned code once. After we get an access_token and a refresh token, we will only use the function refreshToken in our guide (https://gist.githubusercontent.com/wendeehsu/395eaba3fd86eea7b76325cb63bfda71/raw/e3a9953496fb83005ac9bed1c8fbe45c4cf93dcd/refreshToken.py) to renew our access_token with its refresh_token in the future 😘😎
