Hi, I'm new in Odoo14

So, I want the admin account in Settings/Users & Companies/Users to be invisible if the one that logged in is non-admin user. With the code below successfully running on a non-admin account: 

        <record id="admin_user_hidden" model="ir.rule">            

                <field name="name">Only admin can see admin userfield>     

                <field name="model_id" ref="base.model_res_users"/>      

                <field name="global" eval="2"/>            

                <field name="domain_force">[('id', '!=', 2)]field>        

                <field name="perm_read" eval="True"/>

but when I try to login with an admin account a message appears that says:

403: Forbidden

The page you were looking for could not be authorized.

Error message:

Due to security restrictions, you are not allowed to access 'Users' (res.users) records.

Records: Administrator (id=2)
User: Administrator (id=2)

This restriction is due to the following rules:
- Only admin can see admin user

Contact your administrator to request access if necessary.

Implicitly accessed through 'Users' (res.users).

So what's the problem?
