Unable to setup GDrive.

Describe the bug

I want allow my KeeWeb to sync with Google Drive.
I followed the guide https://github.com/keeweb/keeweb/wiki/Dropbox-and-GDrive#google-drive

Now on Google I generated the gdriveClientId and gdriveClientSecret, the guide say to configure that key on the config file https://github.com/keeweb/keeweb/wiki/Configuration#json-app-config I dont understand where I can put the data generated on Google. Where I need put gdriveClientId and gdriveClientSecret?

If I load https://your-keeweb-deployment-url/?config=your-config.json I get Error loading app
There was an error loading app settings. Please double check the app URL or contact your administrator.

I found an online guide, not official that made as file example this:

{
    "settings": {
        "onedriveClientId": "yourcode",
        "onedriveTenantId": "yourcode"       
    },
    "showOnlyFilesFromConfig": false
}

This seems is working.
Now I'm not understanding if for use this for personal use I need insert some privilege on Google settings and have my app verified by Google. Seems hard to configure but maybe is for Google restrictions?!

I continue to get Errore 400: redirect_uri_mismatch
