Updating the Central SMP client example for full DFU support in NCS version 2.6.0 and later

Question

Hi! 
 
 I have tried to implement the following example for NCS 2.6.0 on nrf52840DK: 
 https://github.com/hellesvik-nordic/samples_for_nrf_connect_sdk/tree/main/bootloader_samples/client_smp/smp_client_ble#preparations 
 
 However, there are many issues, especially with Zcbor when using newer NCS versions. 
 
 I have also tried to implement the updates from this official example, and the echo command works, but it is still challenging to make the other functionality work to actually make it usable. 
 https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/bluetooth/central_smp_client/README.html 
 
 Could someone in Nordic take the time to create or update a similar example for full DFU support with central SMP client sample? I am guessing many people need this functionality. Even though I use NCS 2.6.0, upgrading and adapting to the latest NCS is probably the best choice.
