I wanted to run a function that query a given database and removes ppl from the list after 5 days of insertion. I'd like this function to run each 2 hours to check if there's any item that matches this criteria. Is there a way to run this script without the need to import this function in site's page? I tried calling this function in the site's code and it worked however idk if this will only run when there's someone at the website.
