I tried making elemen that only show to utilisator

<div class="col-md-6"
     groups="configurator.group_parameter_administrator">
    <field name="constractor_price"
           attrs="{'readonly':[('state','!=','technical_validated')]}"/>
</div>
<div class="col-md-6"
     groups="configurator.group_parameter_user">
    <field name="constractor_price" readonly="1"/>
</div>

It is working whe I logged in as utilisator

But when I sign in using admin, I can see element that is grouped on utilisator. It shouldn't be visible to admin

The goal is to make that field is editable only to admin. Utilisator cannot edit that field
