Refresh token expires?

[Koniciuaaa]

Hello,

I get refresh token following this instruction:
https://github.com/ivanvermeyen/laravel-google-drive-demo/blob/master/README/2-getting-your-refresh-token.md

It works few days and after that it throws an error: "Daily Limit for Unauthenticated Use Exceeded. Continued use
requires signup"

I tested this few times and always the same. How is it possible?

First looks if your app isn't on test mode on google drive, second if you are using a long runing script, you needs refresh access token, example: masbug/flysystem-google-drive-ext#34

The same is happening here. about a day after I get the token it get expired and I need to follow all the process again. Yes, my app is on test mode still but that is for private usage so there is no terms and conditions page to send to google. will they allow me to make it production even tough that is internal tool?
Can I send to production even if that is not public available?
