There are a few things to note from this video before you try creating your own virtual reality tours with Expeditions Pro.
First, in the demo I used 360 degree imagery that I captured with my Android phone (Pixel 5) and saved in Google Photos.
Second, I downloaded my 360 imagery from my Google Photos account then imported it into my tour.
Third, I used Vocaroo.com to record the audio narration for the each view in my tour. I downloaded my audio from Vocaroo as an MP3 file then imported it into my tour on Expeditions Pro.
