Step 1 : Create new profile and app on Auth0 Management Panel, set your configuration by following docs of Auth0. Download your pre-packed php files from QuickStart step and move them to "adminpanel" folder.. Or create step by step manuelly. You need to be check configurations on settings section and you need to update your changes both two side on your local files(especially .env file) and on settings page(auth0.com) .. Step 2: Go to "sender" folder in main directory and install composer from kreait's php-firebase admin sdk. Update your firebase api info in google-services.json or download json file change with mine.
composer install
Check my db.json , compare with your firebase db. Just it :)
