How to cache bust a Construct 3 game?

Hi,

I added an event to my game to ensure its being launched only on DaggerQuest.com:

However, I missed the ending '/' in the URL string, so now my website is stuck in an refresh loop. I've fixed the URL string and pushed it live, but since the page refreshes before Construct can update, my (hypothetical) players are still stuck in this loop.

I know I can just clear my browser cache and instruct my (totally real) playerbase to do the same, but is there a solution that doesn't involve manual intervention? I've already tried cache busting the iFrame by changing the source, to no avail:

<iframe class="game-frame desktop-only" src="game/index.html?v=72925" allowfullscreen loading="lazy" title="DaggerQuest Game"></iframe>

By far the easiest thing to do is to publish the game to a new URL, and point everyone to that new URL.
