How do I create the best 360-degree photo for Storyline with the iPhone?

Hello everyone!

We are currently testing Storyline, and I’m attempting to create a 360-degree photo. Unfortunately, StreetView, as I know it, is no longer available. What software do you use for creating such images? And what format do you import them in afterward? As an .emf file?

Thank you very much for your assistance, and have a lovely evening!

Kind regards

Frederik
