Display Simscape library or directory as treeview

Hello,

Simscape documentation often displays the simscape packages in the following treeview form:

- +foundation

|-- +electrical

| |-- electrical.ssc

| |-- three_phase.ssc

From: de.mathworks.com/help/physmod/simscape/lang/foundation-domain-types-and-directory-structure.html

How can I reproduce this view (ideally by a command)?

Best,

Leon
