SharePoint Online service worker functionality
Hello, I'd like to understand what SharePoint Online service worker does, and is it possible to register your own service workers? Why I'm asking this - I've registered service worker with scope https://tenant.sharepoint.com/sites/, so that I can intercept events from any site collection in my tenant. But I've noticed that SharePoint Online also has service worker registered in root scope - http://odspserviceworkerproxy.aspx. If I register my service worker with more specific scope, then only my service worker will receive all the requests, say, from site https://tenant.sharepoint.com/sites/xxx. So, what does SharePoint Online service worker do, so I can understand, what will be the impact of adding my service worker? I also had a discussion https://docs.microsoft.com/en-us/answers/questions/454435/sharepoint-online-service-worker-functionality.html, but didn't really get a definitive answer. Microsoft 365 support suggested me to create a discussion here as well, in hopes that some developer will provide information. Thank you!
