Unity web gl build display on a squarespace page

hello, i have troubles to implement / display a little unity build web gl project on my sq page. where i usually would upload to an ftp webspace this isn't possible on squarespace, and dropbox-public folder doesn't allow for that anymore to be hosted at. i want to place a build to present to clients. i am not a developer. i would like to create one new (project) page in my template (flatiron) for it where it runs in the browser. does anyone have a hint if its possible to include a code (what/where)? ANY help highly appreciated, thanks in advance! attached a screenshot of how these files look.
