Insta360 One X stunning use case video

Hi, as promised I m posting the short but spectacular video of my trial of the revolutionary 360-camera. It illustrate the thing, I dreamed to do since I've first found this opening in limestone rock two years before.
No other hardware as far as I know, could help to achieve this effect.
