anyone know how to use intersection observer in a component in a custom event and then getting the event to output and update a variable?

I'm trying to update a variable when this is triggered but i don't see how i can update the variable as i would need an event on something to then be able to get the response right?

Custom actions have an event you can use. If you added the event after the action was set up somewhere you won't see it though, you'll have to re-add it to the workflow

Can you send a screenshot of where you are using the custom action? The custom action has an event which you can use to update your variable
I'm guessing it you are using the custom action onLod of the component?

well i was going to but then if it only does it on load then it won't trigger again when the user swipes right?
to reveal which item in the scroll is 'active'

No, not necessarily
Observers stay until cleaned up, like event listeners, etc
Which is why they need to be properly cleaned or they can cause memory leaks

Just to clarify in case it was misunderstood, it doesn't need a workflow specifically
I was referring to those event flows

You would set your variable on the event flow in your custom action there

yeah so you to get it in an evernt flow it needs to be in a workflow though right?
cause that's what i'm struggling to get my head around
and you saying "event flow" has helped me articulate it!
so my issue is how do i get the custom action into an event flow where i can then update
which is now the case right?

A custom action does not need to be in a 'Workflow' (created on the right panel) to have an event flow, just to clarify
But otherwise, yeah that's how you can set variables from custom action events

From that button in the custom action
The way you're doing in that last screenshot. That button will be there no matter where the custom action is used

Yeah it'll work I'm just clarifying that the custom action does not have to be in a workflow, it can be used on its own
