Reuuzei
To make this work, a google photos API key needs to be added to the app. To do that, go to the google cloud platform, make/use an existing app (if you're reading this and you authored this, you have an app called Reuuzei - shocker).
To add the API keys, go into local.properties and add:
client_id_free=<apikey>
client_id_pro=<apikey)
