Great, looking forward to your feedback.

Yes, this is exactly what the code in the style file does.  And when you
hit `C-c ) RET', hit `c' to narrow down the choices to your environments
defined with tcolorbox-theorems.  This is currently hard-coded.

This feature is also present in current AUCTeX style for cleveref.  I
suggest you remove emacs-auctex-12.1-8.fc32.noarch and install the
latest AUCTeX version from ELPA as described in the manual[1]:

    Simply do `M-x list-packages RET', mark the auctex package for
    installation with `i', and hit `x' to execute the installation
    procedure.

Also read this portion[2] if you install AUCTeX from ELPA.

All AUCTeX/RefTeX features should also work for \label's with optional
argument.

Best, Arash
