Can I install keda + http addon on namespace "A" and use it to scale applications deployed in namespaces "B" and "C"?

[MewanthaB]

I've been trying unsuccessfully to do this. I have installed keda + http addon on namespace "A", and want to use it to scale applications on 2 other namespaces based on number of requests. However, I'm not sure this is possible based on the the documentation

The HTTPScaledObject CRD instructs the operator to install and configure the interceptor and scaler for a specified Deployment. For this to work, you’ll need to have a Deployment running in the same $NAMESPACE

But this other answer here says it is possible. So is the only way the addon will work be if I move both other applications to namespace A? Or can we do multiple namespaces? Just want to confirm since I have been unsuccessful so far and the doc is a little unclear. Thanks!

I am trying to setup in similar way keda + httpadd on is in keda namespace & application + ingress is in app ns. Created Ingress, NGINX Ingress Controller and ExternalName Service setup but so far its not working as expected
interceptor is not reachable from nginx
