Deploying Laravel on Heroku through github getting forbidded 403 page

I am deploying a Laravel application to Heroku. I just installed a Laravel project. But did not make any changes because I installed it just to try out the Laravel deployment on the Heroku. Then I created repository. Then I created a pipeline and a production app within it on the Heroku. Then I synced the production app to the master branch of my Github repo.
This is the screenshot
Then I configured the env variables in the Heroku like this.
When I open or view the app on the browser, it says 403 forbidden. What is wrong with and how can I fix it?

To deploy your application to Heroku, you must first create a Procfile, which tells Heroku what command to use to launch the web server with the correct settings. After you’ve done that, you’re going to create an application instance on Heroku, configure some Laravel environment variables, and then simply git push to deploy your code!
