Hi,

In order to show the button for the limited user, you need to add a user group for the particular button.

To add a user group to the existing button, you need to change the button attribute as follows.

<xpath expr="//button[@name='button_name']" position="attributes">
    <attribute name="groups">stock.group_stock_user</attribute>
</xpath>

You can also add it from the UI as,

Hope it helps
