I’m trying to implement Pushly on Unbounce. One of the requirements is that you host a .js file that serves as a web service worker. The path to this file has to be referenced within the javascript declaration you use to set up Pushly. See reference:
https://documentation.pushly.com/integration/implementation-steps

While this file is a single line that just includes the real web service worker from the Pushly server, it is, nonetheless, required (as per the web service worker W3 Spec) to be hosted as a separate .js file on the same domain as the Unbounce landing page.

Unbounce, CAN WE PLEASE get a way to upload a single file that we can reference via our scripts!?!?

This makes Unbounce a show-stopper for so many technologies like this!
