Hi Bryan,
I'm wondering if you could provide us more details about the following

I haven't seen CCPP used anywhere in the widget space. I'm wondering
if you could provide some more use cases for this requirement? It
seems a bit strong to have this a "must" requirement particularly as
CCPP exchange seems to add quite a bit of complexity to

Kind regards,
