Ionic 5 with Angular PWA not working

Hi,

Does anyone face the issue of not working PWA in Ionic5 with Angular? I am trying below commands to create a simple PWA app with Ionic5 and host the same on the firebase. After I deploy it on the firebase it fails to show the “Add to Desktop” option on the chrome browser.

ionic start myPWAIonic blank

cd ./myPWAIonic

ng add @angular/pwa

ng build --prod

firebase init

firebase deploy

Thanks in advance.
