If not you can still fire the AF360 in dumb slave mode SLAVE-2 (see p 49 of the AF360 manual), but you will need to use manual flash control on the built-in and the AF360 otherwise it will fire on the Pre-Flash of the built-in unit.
I checked the manual again and in the "*" fine print items 5&6 on page 125 & 126 of the manual it states the internal flash can be used as a controller for the AF360 with a 1/3 -2/3 output but it provides no information how to set it up.
I guess it must work in the Slave-2 or dumb slave mode you described or the setup option may become available if the camera detects the flash close by with the internal flash active.
I guess I'm again guilty of following the saying "When all else fails Read the Instructions" so back to Flash manual to figure out how to do it
FWI On the the K500 and the Kr there was an option on the Flash Control Menu that even allowed you to set and sync the communication channels and set the internal flash as the Master & the AF360 or AF540 as the slaves.
With the wireless flash control option missing on the K70 Flash options menu lead me to believe the option was no longer available.
Thanks for giving me an idea where to look and something to try
