[tryton] Where is "Group Membership" page in Tryton client that is in a view in res?

[Fabyc]

Hi everybody.

In the view "user_form_preference.xml" in res I see this:

<page string="Group Membership" col="1" id="membership">
            <field name="groups"/>
</page>


Can you say me in what part of Tryton client is that page?


Thanks
