Trigger a workflow via JavaScript

Questing for the WeWeb team: is it possible to trigger a workflow via custom JavaScript in WeWeb? I have 3rd party forms (Paperform) embedded in WeWeb via custom JS on an HTML element (screenshot here — it was a nice workaround inspired by this comment). Paperform’s JavaScript API has submission events that would be create a nice trigger to a WeWeb workflow (such as a page redirect), but I haven’t found any resources to doing this. So, I’m wondering—is it possible to call a function/workflow …

and

Is there a way to trigger a workflow when a variable changes?

I am setting a variable using Javascript and would like it to trigger a workflow? Triggering a workflow from Javascript could also work in my case.

but I can’t figure out a solution to my particular problem based on either.

Basically, the question is this: how do I trigger a WeWeb workflow from an event in my Supabase backend?
