Hello, I have the following graph which includes a waveform and its mean. Now, I want to add a value in the y-axis that directly corresponds to the mean, as highlighted below.

Is there a way to do this?

Here is an example using text:
rng default
x = rand(5,1);
meanx = mean(x);
figure
plot(x)
yline(meanx,'r')
text(0.6,meanx,sprintf('%6.2f',meanx))

Yes, you could do something like this:
rng default
x = rand(5,1);
meanx = mean(x);
figure
plot(x)
yline(meanx)
set(gca,'YTick',sort([0.1 : 0.1 : 1, meanx]))
I did the sort(), because the ticks have to be in ascending order, and I think that is probably the easiest way.
You could do something more clever with
set(gca,'YTickLabel',<formatted labels here>)
if the higher precision for the mean is a problem.
