I am working on a chrome extension. It has to open up a new window and interact with it once a day and as early in the day as possible. (This has to be done in the user's browser instead of a separate back-end so it can use their session info.) So for example, if not done so already on a given day, then the extension creates a new window, loads up a site, and interacts with it. Then as soon as the next day hits and the user's Chrome is open, the extension will create the new window again.
How can I ensure this window opens up once a day and as early in the day as possible?
I've seen this answer about using alarms to run once a day, but I worry that if I set the alarm to run at 12pm every day but the user doesn't have Chrome open at that time, then the alarm won't run. I've read another answer saying that I can add the background permission to run even when Chrome is closed, but I think that if 12pm passes when their computer is asleep then the process won't run. (However, if I'm mistaken then please let me know.)
