Access simulink model's return values in App Designer

I have a Simulink model that when run either from the Simulink model or the Command Window returns some variables to the workspace. However, this doesn't happen when I run the model from the App Designer. I would like to have access to these variables in the App.

Note: simout only returns the time array and I can't/don't want to modify the model in any way

Use this when running the model:

simout = sim(model,'ReturnWorkspaceOutputs', 'on', 'SaveFormat', 'Structure');
