Odoo User Permission and groups

I was trying to add a new set of permission after technical in user profile page.

But I could not find the code in the odoo folder, all I have got is below

        <record id="user_groups_view" model="ir.ui.view">
            <field name="name">res.users.groups</field>
            <field name="model">res.users</field>
            <field name="inherit_id" ref="view_users_form"/>
            <field name="arch" type="xml">
                <!-- dummy, will be modified by groups -->
                <field name="groups_id" position="after"/>
            </field>
        </record>

I was enthralled why I dont see any text for technical but later realized its autogenerated bu groups. So in order to create new permissions, we need to create our custom group-

In Odoo, to refer the groups category created by odoo, check this page
odoo\odoo\addons\base\data\ir_module_category_data.xml

example on how to add custom permission inside this category - odoo\addons\product\security\product_security.xml
<?xml version="1.0" encoding="utf-8"?>

<record id="group_product_pricelist" model="res.groups">
    <field name="name">Basic Pricelists</field>
    <field name="category_id" ref="base.module_category_hidden"/>
</record>

<record id="group_sale_pricelist" model="res.groups">
    <field name="name">Advanced Pricelists</field>
    <field name="category_id" ref="base.module_category_hidden"/>
    <field name="implied_ids" eval="[(4, ref('product.group_product_pricelist'))]"/>
</record>
