Custom Loki datasource with Application Observability

Hi,

We are utilizing Grafana Cloud but need to keep logs within our own infrastructure such that we have our own Loki instance configured as a datasource via PDC (Private Data Connector). It’s all setup, works great for everything, but in the Application functionality of Grafana Cloud I am unable to select it as the datasource for logs. It doesn’t even show up in the dropdown.

Is there something I can do to get this to work or is this a straight limitation of this functionality? Thanks!
