Can I keep the computer awake using Unity WebGl?

Okay so, I'm building a Unity WebGl app that is targeted at home computers. It needs to be able to keep the computer awake indefinitely.

First t$$anonymous$$ng I tried was the fullscreen option (Screen.fullscreen) but I wasn't super excited by t$$anonymous$$s since Safari isn't supported, w$$anonymous$$ch is a big chunk of users. However, it looks like t$$anonymous$$s actually doesn't work anyway. I'm using a 2015 MacBook pro that's plugged into power, and it still went to a screensaver when I was full screened.

I saw Screen.sleepTimeout, w$$anonymous$$ch I haven't tried yet, but the documentation says that that's only for mobile devices anyway.

Wondering if anybody has done t$$anonymous$$s!
