Template MyTemplate does not exist Odoo 15 - button

Question

Can someone help?
I wan to add a custom button in POS Odoo 15 CE. I followed this article: https://www.cybrosys.com/blog/how-to-add-buttons-in-pos-using-owl, but It's seem that something has changed from verssion 14 to 15.
This is my js file in my_project/static/src/js directory:
odoo.define('numenapp_buyer_name.alias_button', function(require) {
'use strict';
const PosComponent = require('point_of_sale.PosComponent');
const ProductScreen = require('point_of_sale.ProductScreen');
const { useListener } = require('web.custom_hooks');
const Registries = require('point_of_sale.Registries');
class AliasButton extends PosComponent {
constructor() {
super(...arguments);
useListener('click', this.onClick);
}
is_available() {
const order = this.env.pos.get_order();
return order;
}
onClick() {
const cli = this.get_client();
alert(cli.name);
}
}
AliasButton.template = 'AliasButton';
ProductScreen.addControlButton({
component: AliasButton,
condition: function() {
return this.env.pos;
},
position: ['before', 'OrderlineCustomerNoteButton'],
});
Registries.Component.add(AliasButton);
return AliasButton;
});
This is my xml file in my_project/static/src/xml directory:
<?xml version="1.0" encoding="UTF-8"?>
<templates id="template" xml:space="preserve">
<t t-name="AliasButton" owl="1">
<div class='control-button'>
Alias
</div>
</t>
</templates>
And this is my manifest.py file (a piece):
'data': [
# 'security/ir.model.access.csv',
'views/views.xml',
'views/templates.xml',
],
'demo': [
'demo/demo.xml',
],
'qweb': [
'static/src/xml/AliasButton.xml',
],
'assets': {
'point_of_sale.assets': [
'numenapp_buyer_name/static/src/js/**/*',
],
},

The is no qweb entry anymore.
From bundles documentation:
The bundles are defined in each module’s __manifest__.py, with a dedicated assets key that contains a dictionary web.assets_qweb: all static XML templates used in the backend environment and in the point of sale.
Link all qweb .xml in web.assets_qweb bundle like following:
'assets': {
'web.assets_qweb': [
'my_project/static/src/xml/AliasButton.xml',
],
},
