to delete from DB you have to use it's identifier which is a primary key.

a!richTextIcon(
                  icon: "times",
                  color: "NEGATIVE",
                  link: a!dynamicLink(
                    saveInto: {
                      a!deleteFromDataStoreEntities(
                        dataToDelete: {
                          a!entityDataIdentifiers(
                            entity: cons!CDU_CAR_ITEM_DETAILS,
                            identifiers: fv!item.id /*Your primary key value by using fv!identifier in case of gridfield and fv!item.{primarykeyname} in case of gridLayout*/
                          )
                        }
                      ),
                      a!save(
                        ri!itemDetails, /*actual array from where we have to remove*/
                        remove(
                          ri!itemDetails,
                          fv!index
                        )
                      )
                    }
                  )
                )
