Raspberry PI MeshProxy GattService receive notification problem

[Dmitriy D]

I'm trying to create application for working with nRF52 device. I have completed provisioning mesh success, and receive notification message about success operation (work with MeshProvisioning GattService - ok). But when I trying to work with MeshProxy GattService, all commands (such as send AppKey, Reset or Vendor command) send's without errors, and nothing receive in notification. Why notifications not received from MeshProxy GattService?

System info:
Hardware: Raspberry PI 4
OS: Raspbian
Bluetooth: version 5
Soft: Buez + tinyb (java)

Log command Add AppKey:

Log command Send Vendor command:

I think that problem is in enable notification on MeshProxy GattService -> Out Characteristic(00002ade-0000-1000-8000-00805f9b34fb)

Debug information of Mesh mobile application, show this:

It enabled activated by write value to BluetoothGattDescriptor.

When I trying to do the same, I've got an error: Write Not Permitted!
