Will it work while nobody is on the site?

Hello.

I developed a simple React App and hosted it on Heroku.
I need this my app to send some stuff at 00:00 UTC and there is a huge chance that nobody will be on the site at this particular time. Will it work in this case?

thank you for the attention.

No, it only works inside the browser, so if the browser is not the cron is running.
