According to the RFC specifications:
The provided authorization grant (e.g., authorization

- Confirm that you do not have multiple developers testing using the same account, this will lead to multiple tokens being created which will constantly invalidate each other.
- 🆕Check if you have passed the refresh token window (which is 30 days). Once the user gives consent, as we know, the access token lasts for 5 minutes, which you can refresh using the refresh token. This token then lasts for 30 days.
