Problem with Installation

Good morning,

Meanwhile, thanks for the open source plugin.
I installed and activated it, but when I go to my website (https://shop.bottegadelsarto.com) from android or apple, I don’t get a banner or icon to save the desktop application.

I also wanted to know if there is the possibility of adding the app on the app store and google play

This is my configuration: https://prntscr.com/noapf9

Thank you
