Im trying to create an empty PCollection of a custom Object called Incident

public class Incident implements Serializable {
    private Integer incidentId;
    private String appId;
    private Long minutes;
     
   // getter setter 
}

I was trying with the following:

PCollection<KV<String, Incident>> incidents = pipeline.apply("Create Empty Collection", Create.empty(TypeDescriptor.of(KV.class)))
                .setTypeDescriptor(TypeDescriptor.of(KV.class, String.class, Incident.class));

But it gives me compilation error:

Cannot resolve method 'of(Class<KV>, Class<String>, Class<Incident>)'
