How do I select a file to open from folder rather than typing in the csv file name into the code?

Hello, I have the following code where I put in the filename of interest to plot the data into the code. It would much things much quicker and easier if, when I run the code, it opens a folder selection window and then I can select the file or files of interest. How do I open a folder and select a file or files for my plots? Thanks so much!
%Insert csv file name of interest
Pswpdata = readtable('csv_file.csv');
%Compute the max values by the groups of Frequency Variable
T1 = groupsummary(Pswpdata, 'Frequency', 'max');
%Find the indices of the variables to be added
names = Pswpdata.Properties.VariableNames;
str = {'Gain','PAE','PLRF_dBm'};
%Adding 1 to the indices as the output by groupsummary() has an extra
%column for groupcounts
idx = find(ismember(names, str)) + 1;
%Plot the corresponding values
scatter(T1,'Frequency',idx,'filled')
hold on
grid on
legend('Location', 'Best')
title('GT,PAE & Pout (dB)')

Check the documentation on uigetfile which will return the filename and, if you use the two output version, the path to the file selected by the user from a file browser type dialog. For example:
[fn, fpath] = uigetfile;
Pswpdata = readtable(fullfile(fpath, fn));
