No that’s technically not possible. There is no web app that can be installed programmatically. The user always has to do it manually
Could you please try this.
It does actually get downloaded to home screen when u press the download button.
Also the icon in the Home screen is completely like the native apps while when I manually download it it shows Google chrome icon attached to the app icon.
Yes that only applies to android devices and not to ios devices.
Our plugin currently does not support that.
