Where can I find discriptors handle other than cccd, sccd?

Question

Where can I find discriptors handle other than cccd, sccd?
I already know sd_ble_gatts_characteristic_add() return cccd, sccd handles in m_nus->service_handle->cccd_handle/sccd_handle. But I don't know where the rest is in..

If present, the handle of the user description descriptor is outputed together with the CCCD handle and the SCCD handle. 
 Other descriptors should be added with sd_ble_gatts_descriptor_add(), which returns the handle.
