I cannot see ECS Services in list

Does anybody know why I'm not getting a list of running services within my setup? I'm trying to get debug working for a PHP site, and I don't have "Enable Cloud Debugging" as an option, as described here: https://docs.aws.amazon.com/toolkit-for-jetbrains/latest/userguide/ecs-debug.html

I have verified, using my role, I can run `aws ecs list-services --profile dev-admin --cluster {cluster}` and get the list of services.

Does anybody have any idea why I can't get a list of services within Intellij? When I right-click on my service in the viewer, all I get is "Disable Command Execution"; I don't see "Enable Cloud Debugging" as described in the docs.
