XF 1.4 Add attachments to conversations permissions

[rwm1962]

I can see from the linked thread this can be done:
https://xenforo.com/community/threa...now-implemented-for-licensed-customers.74901/

I want to limit this to a certain group but can't find where to set the permission.

Can someone point me in the right direction please?
