You can link your own created Google App instead of relying on the default plugin app. By following the guidelines below, you can easily create your own Google App and integrate the custom app with the Integrate Google Drive plugin.
NOTICE: Google will automatically revoke authorizations after 7 days for Apps that are in the ‘Testing’ status. After that period, you will have to re-authorize the plugin itself. So if you want to use your own app, you will have to submit the app for verification via your Google Cloud Console in order to get the status ‘In production’ and to be able to actually use it with the Integrate Google Drive plugin. Or you can revert to the default app of Integrate Google Drive which is published by Google.
NOTICE: If you encounter any issues when trying to use your own App, please revert to the default app of the plugin by turning off the Own App option from the Advanced settings.
