We could research "preloading" our app on startup somehow? There seemed to be an attribute responsible for that in appinfo.json (similar thing is done for YouTube, which, at least for me, seems to run in the background constantly...)

Another way is to do this job on another machine. Because this works anywhere if you hold the token. (I didn't find any official way to do auto-start without root)

I could implement on this project instead: https://github.com/webosbrew/DevModeMgr

Considering the behaviour of YouTube TV app (looking at luna-send -f -i 'luna://com.webos.applicationManager/running' '{"subscribe":true}' after a reboot), it looks like webos-preload-manager automatically starts up some apps in the background - maybe we could use that to launch homebrew channel for a second to renew the token and then just quit?
