How would I import a spine image, .json file, and a .atlas file into an HTML Document to display an animated model?

I’m wondering how I would be able to import something from Gimkit into a site I’m creating without having to download the actual file itself, and I’m trying to use a singular HTML Document to make my site. The animated previews use a spritesheet-like thing made in Spine, a .json file, and a .atlas file. I am hoping to eventually make this usable for all filenames, but for this example, I need to use the filename “dayOne”. The spritesheet can be found at https://www.gimkit.com/assets/map/characters/spine/dayOne-v2.32.png, the .json file can be found at https://www.gimkit.com/assets/map/characters/spine/dayOne.json?cb=410516585127, and the .atlas file can be found at
https://www.gimkit.com/assets/map/characters/spine/dayOne.atlas?cb=410516585127. If anyone could do this for me, I would be forever thankful! Thanks!

I have tried several things, but I honestly have no clue on what to do with this. I tried this, based on some information I previously found online, but is doesn’t work. If you could help me, that’d be great!
