HTMLAnchorElement.download doest'n work in Oculus Browser

[ClickONru]

Hi, guy's.

Perhaps someone has encountered this problem:

I'm trying to create a download link programmatically but have no success.

 How can this be fixed?

const json      =   JSON.stringify(someJson);
const blob      =   new Blob([json], {type: 'application/json'});
const url       =   URL.createObjectURL(blob);
const a         =   linkElement; // HTMLAnchorElement
a.href          =   url;
a.text          =   url.toString();
a.download      =   'some-file-name';

When i click on link nothing happened.
Without "download" property this link open like a document.

Thank you for help

i found "solution" - any files is downloading silently (without any warns for user).
I prefer for browser somehow warn me about any downloading. But in general its work.
