Thingy:52 read passive NFC tag

Hi,

I'm trying to read a passive NFC tag with the Thingy:52. However the NFCrx event seems to not work. I implemented the following methods based on the API ref:

NRF.on('NFCon', () => { console.log("Tag detected!"); });
NRF.on('NFCrx', (arr) => {
  Serial1.println(arr);
});

Did I miss something, or is there a different way to do it?

Thanks!
