PWA : seeing the browser address bar in my app on Android ( uploaded to play store)

Hello! I trust everyone is having a great day.

I utilized https://pwabuilder.com/ to generate an .aab file and successfully uploaded it to the Google Play Store.

After the app signing process, I copied the new SHA-256 fingerprint from the Google Store to the assetlinks.json file and uploaded it to sitename.com/.well-known/assetlinks.json.

However, despite these efforts, I still observe a browser address bar in the Android version of the app.

It's worth noting that when I download the app via PWA from the browser, the address bar is not present. Could you kindly assist me in identifying any missing steps?

Thank you very much for your help!
