req.onsuccess = (e) => {
if (req.result.length > 0) {
req.result.forEach((result) => {
console.log(
`Existing registration ${result.pushEndpoint}${result.version}`,
);
});
} else {
const register = navigator.push.register();
register.onsuccess = (e) => {
console.log(`Registered new endpoint: ${register.result}`);
