How to add Mean and Median to a boxplot?

I am ploting a boxplot using inserting data from an Excel file.The excel file is attached. I want add Mean, Median and their legends to the Boxplot. The code I am using is as below:

sample=readmatrix(file.name)

x=sample(1:end,1);

xString=string(x);

dataSample=sample(1:end,2:end)

boxplot(dataSample)

and The plot is like This:

My problem is that I need both Median and Mean of the data for each series of the data. However the plot is only showing the Median. Can any one help me with adding a line for Mean like the one was added for Median? Thank you

sample=readmatrix('Data.csv');
x=sample(1:end,1);
xString=string(x);
dataSample=sample(:,2:end);

%Calculate mean
m = mean(dataSample, 'omitnan');

%plot the boxchart and get the handle to the boxchart object
b = boxchart(dataSample);

%get the width of the boxes;
width = b.BoxWidth;

%position data of boxes
x = double(b.XData);

%Data to plot individual lines for mean values
X = [x-width/2; x+width/2];
avg = [m;m];

hold on
%plot the mean values
plot(X,avg,'r')
