Angular material tree checkbox with real example

I saw almost all examples about how to work with angular material tree checkbox such as official example and this.
In this examples used string array structure. but how can I transform a real nested object array structure to angular material tree checkbox?
My structure:

As you see the data that received from the server, say to the client that which item checkbox value is true. and 'Id' must be bind to the tree because of I send this field to the server when user submit the form.
This structure is correct? and how can I mapping to angular material tree chechbox.
