How to add a 128-bits custom uuid in BLE advertising data?

[Noxstella]

In my project, my master controller need to scan devices through custom uuid.

One problem is that in ble_advertising_init, I can only add 16bits uuid and type of which is BLE_UUID_TYPE_BLE(Bluetooth SIG UUID)

How can I add a BLE_UUID_TYPE_VENDOR_BEGIN uuid and show complete 16 bytes uuid in advertising data?
