VSCode and CSP - what did I miss?

Hi -

I'm trying to get my VS Code instance that is connected to an AWS IRIS instance to edit/save/compile .csp files, but it's failing to work and I'm not sure why. The ".csp" is associated with the objectscript-csp code, and the server is connected, but things just don't act like they are enabled.

Should this work? and if so, what might I have missed in configuring things?
