SAP CAP - @Capabilities Annotation

Hi Experts,

SAP CAP documentation mentions that services can be annotated with OASIS annotations over @Capabilities.

https://cap.cloud.sap/docs/advanced/odata#annotations

If for example, we want to make an entity or service not insertable, how our CDS are to be extended to properly include the @Capabilities annotation with insertable to false?

Thanks!
