User Own Company Access Rights Odoo App helps only to access those companies which are assigned to users as allowed company on user form. On default odoo all users can see all the companies whether it's allowed or not than if the user have "Administrator/Access Rights" group then the user can update allowed companies from the user account and add more companies access to their own user. This app helps users to restrict the company access to users and make limited company access as allowed companies given to user access. Thia odoo apps added one group which is "Own Company Access" if a user has ticked, then these users will only have access to this assigned allowed companies and this user can assign only those allowed companies to new users.
