Buddypress Activity Plus for BuddyPress Groups - Not showing on custom template

Hi -

We're coding up a Buddypress site including the great Activity Plus plugin.

Activity Plus is showing/working fine in standard BuddyPress Group templates. However, we're coding some bespoke taxonomy pages that pull in a BuddyPress Group Feed/Activity form, and it's not showing under the form on this bespoke template.

I guess Activity Plus may need some hook that we've not included in our template, or maybe it does a check for Buddypress page? Can you help resolve?

I've included the code we're using for the form in our bespoke template below.

Cheers
Marcus
