hello. I want to create a new webpage in the module website_sale
I entered into the website_sale/views/template.xml and added a page called offer.

The header of the page is:

<?xml version="1.0"?>

<t name="Offers" t-name="website_sale.offers">

<t t-call="website.layout">

<t t-set="additional_title">Offers</t>

And so on...

I can easily see and modify the page into my view manager into Odoo. But i cannot display it in the frontend in /shop/offers.
Why? How to add a new page? I cannot do it from the front end because i need to import stuff from the module itself
