Service worker and payment Handlers - service-worker

Question

I created a service worker for a payment manager. When I checked the server is installed but I do not see the payment methods installed on the browser.
i added the event install fetch and load but i can't show the payment methods register in browser..
Any help please
My installer is
navigator.serviceWorker.register('sw.js').then(() => {
return navigator.serviceWorker.ready;
}).then((registration) => {
if (!registration.paymentManager) {
console.log('No payment handler capability in this browser. Is chrome://flags/#service-worker-payment-apps enabled?');
return;
}
if (!registration.paymentManager.instruments) {
return;
}
registration.paymentManager.instruments
.set('instrument-key', {
name: 'Chrome uses name and icon from the web app manifest',
enabledMethods: ['https://...'],
method: 'https://...',
})
.then(() => {
registration.paymentManager.instruments.get('instrument-key').then((instrument) => {
}).catch(...
})
My server worker
let payment_request_event;
let resolver;
let client;
const addResourcesToCache = async (resources) => {
const cache = await caches.open("v1");
await cache.addAll(resources);
};
self.addEventListener('install', event => {
event.waitUntil(
addResourcesToCache([
"/",
"/index.html",
])
);
console.log(`SW: Event fired: ${event.type}`);
console.dir(event);
});
self.addEventListener('activate', event => {
console.dir(event);
});
self.addEventListener('fetch', event => {
event.respondWith(fetch(event.request));
});
self.addEventListener('canmakepayment', e => {
console.log('canmakepayment', e);
e.respondWith(true);
});
self.addEventListener('paymentrequest', async e => {
console.log(e)
payment_request_event = e;
e.respondWith(resolver.promise);
// Open the checkout page.
try {
// Open the window and preserve the client
client = await e.openWindow('https://...html');
