Prompt user to load data file

I am creating a pop-up menu as part of a final project for one of my courses. One option on this menu will ask the user to load a data file, I'm not sure how to ask a user which file they would like to use. I know how to load data files into arrays, but I don't know how to build a prompt that will ask "which file." Preferably I'd like it to open a file explorer in which you select a file, but I'm not sure if this is possible.

Here is what i have. The prompt to select a file to load into an array would be case 2.

choice = 1;
while choice ~= 11 

choice = menu('Statistical Analysis','Set username','Load data file','Clear data','Set output filename','Plot histogram','Plot histogram fit','Plot probability plots','Regression of y on x','Find probability (x or z)','Find x or z','Exit')

switch choice
    case 0
        close all
    case 1
        username = input('Please input your username:\n','s')
    case 2
        x = load('input')
    case 11
        close all
end
end

Take a look at https://www.mathworks.com/help/matlab/ref/uigetfile.html it might be what you are looking for. You can filter by file type as well so below I look for all csv files and then load the selected file.

 %Shows all files with a .csv extension
 [FileName,PathName,FilterIndex] = uigetfile('.csv')
 C = csvread(FileName)
