Can't open demo?

I am trying to open this demo, but it says 'No system or file called 'pidtune_demo' found.'

https://www.mathworks.com/help/sldo/examples/pid-tuning-with-actuator-constraints.html

I'm using R2020a. Help?

I guess more importantly, I'm trying to find out what kind of block the output constraint and actuator constraint is as well.

This example requires Simulink Design Optimization and pidtune_demo model is located under this toolbox.

$MATLAB_INSTALL_FOLDER\toolbox\sldo\sldodemos\optim\pidtune_demo.slx

Please confirm you have installed Simulink Design Optimization.
