Shiny and Squarespace




I am trying to figure out if it possible to upload my shiny app to a website hosted by squarespace. I have read this feed, which was super helpful: Embedding apps in website

However, I am trying to avoid shelling out even more money, when I am already paying for web hosting. Squarespace does allow embedded html and code blocks. I've seen shiny apps appear in iFrames on squarespace sites, like here:

But this site uses AWS to support the app. Is that the only way? I'm new to this, so if I am missing a step, forgive me!
