How to run a Simulink Desktop Real-Time model with external mode in an App Designer app?

I need to create an app that runs a Simulink Desktop Real-Time model in the external mode, like this

In the MATLAB app, I set up a button callback function to start my simulation, like this

set_param(MyModel,'SimulationCommand','start')

But I noticed that the simulink model seems to work in the Nomal mode, shown as

What should I do or set parameters to make the model run in external mode in my designed app.

Any information will be helpful and thanks in advance.

You can utilize 'slrealtime' .

Like,

>> tg = slrealtime;

>> tg.start();

https://www.mathworks.com/help/slrealtime/api/slrealtime.target.slrealtime.html

The brief workflows are,

1. Build model

>> rtwbuild('mdl'); % or slbuild('mdl');

This generates mdl.mdlatx file.

2. Load model

>> tg.load('mdl')

3. start model

>> tg.start();

You can easily utilize using 'slrealtime' obj.
