How would I test to see if my datastore code works without uploading my game for others to play?

So I have a game I have been making & I am no where near being able to release it but I just added some datastore code, but I get an error saying I have to publish this place to the web to access datastore. So is there any way I test the datastore without publishing it to the web for others to play?

1st method: Go to your game's page > Configure Game > Enable Studio access to api services then enable it and click save. After that go back to studio and click play.

2nd: Make your game private by going to your game's page> Configure game > Private (Click it) > Save then publish your game. Go back to your game's page and simply just click "Play" . Only you will be able to play it if its private.
