Hi
I'm trying the solution from the link above.
I need to add <link rel="manifest" href="manifest.json"> into page's HEAD. How can I do it? Is it possible through javascript in the same way as I inject my own icon?

Code:

$(function(){
new_path = '/scada/resources/icons/favicon.png'
$('head > link')[3].href= new_path
$('head > link')[4].href= new_path
});

I need to store manifest.json file in LM. Can I do it in Images/Background, icons etc? Is there a better solution?

Thank you
