cannot open the call C Functions Using CCaller block in MatLab?

whenever I try to run the example below in the link: https://nl.mathworks.com/help/simulink/slref/call-c-functions-using-c-caller-block.html

but I alwys get this error. do I miss the example itself?

>> openExample('simulink_features/CallCFunctionsUsingCCallerBlockExample')
Error using exampleUtils.componentExamplesDir (line 13)
Invalid argument "simulink_features".

Error in findExample (line 18)
    componentExamplesDir = exampleUtils.componentExamplesDir(component);

Error in openExample (line 24)
metadata = findExample(id);

Hello MATLAB developers,

I am also getting same error, which is given below

Error using exampleUtils.componentExamplesDir (line 16)

Invalid argument "simulink_features".

Error in findExample (line 18)

componentExamplesDir = exampleUtils.componentExamplesDir(component);

Error in openExample (line 30)

metadata = findExample(exampleId);

I am using MATLAB 2020b. Can somebody tell me what is the problem over there?

Kind regards
