JavaScript - PWA - possible to send and receive data using NFC

I need to implement NFC (near field communication) in a PWA (progressive webapplication).

I use this code but not worked:

Writing a string to an NFC tag:

if ("NDEFWriter" in window) {
const writer = new NDEFWriter();
await writer.write("Hello world!");
 }

Scanning messages from NFC tags:

if ("NDEFReader" in window) {
    const reader = new NDEFReader();
    await reader.scan();
    reader.onreading = ({ message }) => {
   console.log(`Message read from a NFC tag: ${message}`);
   };
}

Is it possible to use NFC in any way in a PWA?
