XF 1.3 how do i add content to a specific forum/page using hooks?

now i sort of understand hooks and how to use them but i am unsure how to make it set to that only page not to the entire node list/forums

as you can see in the images i see a hook page_container_breadcrumb_bottom but this will apply to all the forums how do i hook it only to the pages/vip-shoutbox page only and no where else?

i want to do something like this:

<xen:hook name="dark_taigachat_online_users" params="{xen:array 'room=2'}" />

but only on that specific page...
