How can I have Model InitFcn Callback generated in model Init function using Embedded Coder?

I have a model which is doing:

output = input + par_init + par_edit

• par_edit: shall be tunable, to set this value externaly before running the generated code. 
• par_init, is calculated from the first parameter par_edit, and defined in Simulink in the Model-Callback InitFcn.

The generated code looks like

/* Model step function */
void ModelInit_step(void)

{
ModelInit_Y.Out1 = (ModelInit_U.In1 + 6.123233995736766E-17) + par_edit;
}

/* Model initialize function */
void ModelInit_initialize(void)

{

}

Model initialize function code could be generated in the following methods:

• Using the Initialize Function, which executes contents on a model initialize event, instead of the model callback InitFcn. To access the release-specific documentation in MATLAB R2019b, please run the following command in the command window:

  >> web(fullfile(docroot, 'simulink/slref/initializefunction.html'))

• By specifying Configuration Parameters > Code Generation > Custom code to include in the generated model. To view the relevant documentation in MATLAB R2019b, execute the following command:

  >> web(fullfile(docroot, 'rtw/ref/initialize-function.html'))
