How do I find the library block path of a built-in Simulink block to add it programmatically to my model?

I want to programmatically add a Simscape Connection Port to my model. But in order to use the "add_block" command, I need to know what the library path is for the Simscape Connection Port. How can I programmatically add the port using the MATLAB command line?

In general, if you want to find the root library of most of the built-in blocks, you can use one of the following methods:

(1) Go to the Library Browser and hover over the block:

(2) Go to the Library Browser, right-click on the library of interest and select "Open <libraryname> library" to open the library model:

Then in the library model, select the block of interest, and enter "gcb" at the command line:

>> gcb
ans =
    'nesl_utility/Connection Port'

(3) A possible programmatic solution to finding the library block path for blocks from the basic Simulink library is presented in the following MATLAB Answers post:

Finally, if your model is called "modelname", use the following command to add the built-in library block to your model:

>> add_block('nesl_utility/Connection Port','modelname/MyConnection')

Refer to the "add_block" documentation page for more information:
