How to embed a command prompt into an mlapp?

I'd like to embed a command prompt into an mlapp. Basically, recreate the Command Window within my own custom mlapp. I would like the usr to receive instructions and notifications within this console, and I am also using a tcp connection to run a python script so it would be nice to not have a separate windows popping up for all of these interactions.
Would this require some significant MATLAB-java backend programming? Or is there a built-in functionality with the 2020b AppDesigner?

I'm also curious about the not-compiled approach with interactive Matlab session.

I would be also interested in this. As an alternative to see the outputs from the command window, I use diary and fread in combination with Text area with turned off ability to edit.
If you run MATLAB through actxserver, new instance opens, with only a command line,
Matlab_COM = actxserver('Matlab.Application')
It would be great if it would be possible to attach it to current running instance of MATLAB, but I wouldn't know if it can be done, or if it's possible.
Matlab_COM.Execute("a = 'this is cool'");
% In this separate instance
» a
a =
'this is cool'

Compiled would be a problem. Compiled does not have access to evaluating user input as commands.
Compiled does not stop you from defining a command language and parsing it and having a data structure that you use to chain together pieces. On the other hand, the more flexible you make that command language, the more you would have to worry about being in violation of the license agreement.
