how to set disclosure indicator for label

[appsird]

I define a label as follows:

struct Static {
    static let label = "label"
}

let row = FormRowDescriptor(tag: Static.label, type: .label, title: "my title")

For certain labels, I would like to add a disclosure indicator '>' at the end of the row.

I override the following method to determine which row was tapped:

override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {

}

I then use a segue to bring up the appropriate view for the row. Thus, how can I add a disclosure indicator to an arbitrary label line.

I tried:

row.configuration.cell.appearance["accessoryType"] = UITableViewCellAccessoryType.disclosureIndicator as AnyObject

Though, this errors out. Thank you for reading, and appreciate any thoughts on this happen.
