gopro fx reframe motion blur not working

Hello.. 

we have more than one mac machine,

and we have tried to apply (GoPro Fx Reframe plug-in) in premiere pro 2019

but motion blur does not work.

on the other hand, when we apply the plug-in in after effects 2019, motion blur works fine.. 

we have a huge film filled with 360 Footage..and we really need to use premiere pro without migrating to After Effects each time we work on a 360 footage..

can you please help??
