4th axis simultaneous chamfer milling on 640t SQT100MY

Hello!

Quite a beginner here so please be patient. :-)

I'm trying to do the chamfer on the picture I've attached on my Mazak Super Quickturn 100 MY using Mazatrol programming on the Fusion 640T controller, but the question is: Is it even possible?
I can easily create the pocket of course but that won't need to involve the C-axis as the chamfer will need.
People are telling me to use "inside chamfering" but I can't seem to find that unit on the machine, in the manuals or on the internet so I'm starting to think this might not be possible at all - and if so, how would I go about to solve the customers problem?
Sorry for the Swedish on the controller photo but I seem to be stuck with that.

I managed to get it working in Fusion 360 and get G-code in just a few minutes, but I'm not sure that will help me ..

Any help would be greatly appreciated, thank you.
