To generate a Google refresh token, you'll need to follow these steps:

Go to the Google Cloud Console (https://console.cloud.google.com/)
Create a new project or select an existing one.
In the project dashboard, click on the "APIs & Services" option from the left sidebar.
Click on the "Credentials" tab.
Click the "Create Credentials" button and select "OAuth client ID".
Choose "Desktop app" as the application type and give your client ID a name.
Click "Create".
Once the client ID has been created, click on the "Download" button to download the client_secret.json file. Keep this file secure as it contains sensitive information.
In your code, use the client ID and client_secret.json file to obtain an authorization code.
Exchange the authorization code for a refresh token by making a POST request to the Google authorization server. The request should include the client ID, client secret, authorization code, and grant type. The response will include a refresh token, which you can use to obtain new access tokens as needed.
