Spline Feature within CMS


I have just bought a template for my 3d assets I build with Spline. Now I want to embed the spline design into each cms page which represents one of my 3d art works. However this does not work as the cms does not offer this option. What other ways are there there to embed the 3d file directly within the cms page?

Thanks for the help!!

Good day, I too am looking for a similar solution using spline in cms. Were you able to discover a way to do it?
