[DOC] Undocumented libraries

[Kochise]

Hello,

we have https://github.com/espressif/arduino-esp32/releases/tag/3.3.6 as of today.

Thus https://github.com/espressif/arduino-esp32/tree/3.3.6/libraries as Libraries :

Yet the documentation only shows https://docs.espressif.com/projects/arduino-esp32/en/latest/libraries.html as Features :

And documented APIs :

Which makes the following Libraries "potentially" undocumented, or APIs orphan of a Library :

Could you clarify ?

Where is the documentation of, say, https://github.com/espressif/arduino-esp32/tree/3.3.6/libraries/FS ?

I can't rely of the comments inside the source code.

Regards.
