How to display names in edit field of the files selected to run .m file using button in appdesigner

Hi I have a .m file which I wants to run using button function.

The .m file asks for the two input .mat files to be selected to execute

How can I display the names of the two input .mat files selected in the edit field boxes.

%%%%%%%% main model for reference
function RunModel
    MFilDirName='ModelScripts';  %% Sub directory contains the supporting .m files/functions   
    addpath(MFilDirName)  %% Add this subdirectory to the Matlab search path
    
    if strcmp(LoadFiles(2),'EndExit') %% Load file is a .m function inside ModelScripts
    disp('User abort')
    return
    end
end

%%%%%%%%%%%%%%% App designer run button
function RunButton(app, event)
    RunModel;
end
