I developed a Chrome browser extension and converted it to a Safari iOS browser extension through xcrun. I found that when running the plugin in Safari on iOS, it runs for about 5 minutes continuously. After manually locking the screen, then opening and refreshing the page, I noticed that the service_worker seemed to have been uninstalled. I tried sending a message to it through chrome.runtime.sendMessage, where the service_worker simply returns a fixed string, but what I received was undefined.
