How to get published html onto website?!

Hi! So I just downloaded Edge Animate CC yesterday and have very little experience with it. I want to integrate animation into pictures and infographics on my organization's website. I did a quick animation and published the file. However, I was then at a loss as how to actually upload the html file to my website. Now, we have had a developer design our website and it is their CMS that we use to add content to the website. I have very little experience with HTML and website coding. Please keep that in mind. My question is how on earth can I upload the file to the website? The file is on my hard drive so any coding I do doesn't work because the website has no idea where to get that file. I know that isn't a lot of details but I can provide more if anyone specifically what my problem might be!
