I have created a VR tour, using https://www.theasys.io/
however, I am unable to upload it to Sketchfab and thus my portfolio page. This is because it is an incompatible file format to those supported by Sketchfab.
Theasys does give me a URL for embedding or alternatively html code to embed it directly (please see attached).
As this is the main outcome of my final project, it is essential that it is featured on my portfolio page. Hopefully, technical support can resolve this using one of the mentioned methods.
