How does Metamask persist the background script?

Hi all! I wanted to ask how does MetaMask persist the service worker? I mean, with manifest v3 now service workers should go inactive after 5 minutes of inactivity, but how does MetaMask prevent this from happening? Thanks :slight_smile:

If anyone has the same question, after reading the extension code, I found that they use a “keepAlive” function which the content script executes every 1 second, for 45 minutes. This way, if there is any active tab, it will keep reviving the service worker. Cheers!
