Tags not getting triggered at Checkout Page and Thank you page

[thingsontheway]

Hi Team

Tag are not getting created after installing GTM. 

This is the code I have added in pixel 'Customer Events' section

(function(w,d,s,l,i){w[l]=w[l]||[];w[l].push({'gtm.start':
new Date().getTime(),event:'gtm.js'});var f=d.getElementsByTagName(s)[0],
j=d.createElement(s),dl=l!='dataLayer'?'&l='+l:'';j.async=true;j.src='https://www.googletagmanager.com/gtm.js?id='+i+dl;f.parentNode.insertBefore(j,f);
})(window,document,'script','dataLayer','GTM-XXXXXXX');

analytics.subscribe("checkout_completed", event => { 
  window.dataLayer.push({
    event: "purchase",
    order_id: event.data.checkout.order.id,
    price: event.data.checkout.totalPrice.amount,
    currency: event.data.checkout.currencyCode,
  })
});

Here Thank you page will be added, it will be crossed out as well stating no tags found. 

Could you please help?
