How do I program my app to export a file to Windows File Explorer?

I am currently designing an app using Matlab's App Designer that processes audio and my query is very simple: I want to program a button so that when it gets pushed a Windows File Explorer (or Finder in OS) window shows up and I can save my file with a specified name and location as I would normally proceed in any other standard program.

I already know of '[file,path]= uiputfile({'*.*'});' but it doesn't create any file when I save it..

I have to join it with this line of code 'audiowrite(filename,app.audio,app.fs);' but I'm not sure how to!

Please help guys! Thanks in advance!

[file, folder] = uiputfile('*.wav');
if ~isequal(file, 0)  % User did not press Cancel:
  audiowrite(fullfile(folder, file), app.audio, app.fs);
end

Compare this with the example for xlswrite at the bottom of the documentation: doc uiputfile (link)
