Captive 2019 VR: any other publication options?

I see on the support page for creating VR content with Captivate 2019 that Samsung Gear VR and Daydream VR are the only listed publishing options. Content I've created plays fine through a browser on a computer, but I don't have access to the Android gear that the VR publishing options require.

Anyone know of any other VR publication options at this point, or if there are any plans (or maybe even rumors) to use any other platforms, or platforms like Daydream VR to accept iPhones?

Tnx.
