How to include Simulink directories within a compiled app using App Designer?

I am working on compiling an app that runs a simulink model on a target computer. The app runs fine from within app designer. However, we would like to compile the app into a standalone application that can be run by simply clicking an icon on the desktop.

I have been running across the error shown in the below picture and am unsure how to solve the problem.

The MATLAB Path must have these directories for Simulink to function:
  toolbox/simulink/blocks, toolbox/simulink/simulink
MATLAB cannot continue. Please restore the path and restart Matlab.
Error in => <...>.mlapp at line x

I tried using the "addpath" command. However, modifying the search path is apparently not supported by Matlab Compiler.

I also tried adding the relevant folders shown in the error message to the application by including them in the "Files required for your application to run". The "toolbox/simulink/simulink" folder could not be read for some reason and the inclusion of the "toolbox/simulink/blocks" had no affect on the resulting error message.

Finally I tried including dir("C:\...\toolbox\simulink\...") within the app code's set up function (line 639 of the app's code executes the set up function and the set up function attempts to access the simulink model). This also had no effect.

Any suggestions? Thank you for your time

Note that deploying Simulink models or functionality to a standalone executable requires the Simulink Compiler product: https://www.mathworks.com/products/simulink-compiler.html
