Unable to install within namespace

I'm trying to facilitate use of gitlab-agent with on-premises TrueNAS SCALE appliances.

The appliance offers an app catalog using K3s and Helm. The user selects a chart in the UI and populates form values; middleware then sets up a namespace and a restricted service account and attempts to install the chart from therein.

This installation currently fails, apparently trying to install a ConfigMap globally?

I've drafted !14 (closed) hoping to elide the ConfigMap when it's not needed for a caCert.

If there's a more surgical/correct way to address this use case, please clue me in. Thanks!
