Does anyone know if there is a way to do this?

Our game is currently set to a downloadable game, but I want to make it easier for people to play and make it directly playable from the browser. Thing is, the game is a PWA which we host ourselves. Also, we update the game daily (sometimes multiple times per day) and it's not doable to upload a new version to Itch every time we update. That's why we'd like to run the game through an iframe, but there seems to be no option for that under "kind of project" in the game upload menu. 

Help would be great :)
