DFU Device with Zephyr & MCUboot over SMP

[eshaulx]

question here,
I am using nRF52840 device with zephyr application & MCUboot + SMP service
the DFU is now done using: https://github.com/apache/mynewt-mcumgr-cli using actual CLI commands.
(or using Nordic connect mobile application)
the connection is done via BLE - so far so good,
now I want to integrate the DFU process into my proprietary GO application running on a Linux machine.
I am new at GO, and trying to understand how to integrate that with my GO application.
I understand that the CLI is a wrapper of the actual library :
Do i need to add the https://github.com/apache/mynewt-newtmgr as go module and use it? if yes, how can i use it?

I took a look in the code & documentation but still have no understanding of how should i use the library as it is built on CLI interface - commands are built & executed using the arguments given from the CLI command, for example:
resetRunCmd from newtmgr/cli/reset.go is not exposed outside so i don't really understand how to use it...
I feel that i am missing something here...
I found no other examples or other cases in which users used the library in their own applications.
Thanks in advance guys!
