Downloading files on background

[craftercis]

Hey people,

Is it possible to create an app in which people have to give permission to have these files downloaded in the background so that they can then use my AR functions on the site? And how do I deal with this? IOS 12 has recently introduced an option for developers to create a button that immediately enables AR on their website (AR Quick Look). Unfortunately this is not yet for chrome (google). That is why I hope that the above idea can work

UPDATE:

I just read that these files are implemented in an unstable version of chrome called: Chrome Canary. I would like to know if this version of Chrome will actually come in the normal chrome in the future.
