Intercepting file download in chrome
Here is a little JS snippet which prevents every file download  (and accessorily opens a new tab in Gsuite for attempts to download from the Gsuite):        chrome.downloads.onCreated.addListener(downloadItem => {        chrome.downloads.cancel( downloadItem.id, ()=>{          alert("DL canceled: "+downloadItem.finalUrl);          if (downloadItem.finalUrl.search("https://docs.google.com")!=-1){            var _driveUrl = downloadItem.finalUrl.replace(/export\?.*/,"");            chrome.tabs.create({url:_driveUrl}, ()=>{});          }        })     });
