You could post it as a subject in the community with the link, if voting doesn't matter to you. BUT there's another way to submit it, so!
If you export it into it's own file, then you can publish it as a downloadable book! Then you click "submit" (when the game jam opens.) And click to pick your project and submit. So either or! Remember, you can submit as many things as you want. Does this work for you?
