How to save a file by taking the folder path and filename as input from user in MATLAB app designer?

I have written the below code to save the file in .mat format and it is working.

However, I want the user to select the specific folder and also the name of file before saving it in every insatnce.

function SaveButtonPushed(app, event)
            
app.filename = strcat(app.filename,'.mat');

toBeSaved = struct('para_BF_new', app.para_BF_new);
if isempty(app.FLG)
    toBeSaved.ROI = app.ROI;
end
if isempty(app.FLR)
    toBeSaved.para_FLG = app.para_FLG;
end
if isempty(app.FLFR)
    toBeSaved.para_FLR = app.para_FLR;
end
toBeSaved.para_FLFR = app.para_FLFR;

save(app.filename, '-struct', 'toBeSaved')

Hello,

Check here

[baseFileName, folder] = uiputfile('Specify a file');
fullFileName = fullfile(folder, baseFileName)
save(fullFileName,'-struct','toBeSaved');
