How do I generate this figure? (I can't produce bold edges)

Hi, everyone.

My code is below. But I have to modify the code because I want to generate a sign with bold edges (like the following figure). Can you help me with this? Thank you so much.

t =(1:4)'*pi/2; 
x = sin(t); 
y = cos(t);
fill(x,y,'y'); 
axis square off;
text(0,0,'WAIT','Color', 'k','FontSize', 80, ...
'FontWeight','bold','HorizontalAlignment', 'center');

Add the following line:

t =(1:4)'*pi/2; 
x = sin(t); 
y = cos(t);
h = fill(x,y,'y');                      % Get the handle
h.LineWidth = 5;                       % Add this line
axis square off;
text(0,0,'WAIT','Color', 'k','FontSize', 80, ...
'FontWeight','bold','HorizontalAlignment', 'center');
