Task:
    Initially the attachment button is visible to everyone,  but If a checkbox is tick (True).
    The button should only be visible to a certain group.

    I tried putting the group on the 'groups' parameter of the button and it works, but what I want to achieve is to do it dynamically (based on the checkbox's state).

Please advice, and I appreciate if you put a sample code.
Thank you so much Odoo Community.
