# texstudio completion of ntheorem commands

I want to have Texstudio add completions for some ntheorem package commands, including:

\begin{Definition}[]
\end{Definition}


and

\begin{Proposition}[]
\end{Proposition}


I looked at the CWL file and could not find references to any of the \begin{} and \end{} environment definitions, so I was not sure how to add these. Any suggestions on how to include this syntax in the ntheorem.cwl file?

As a reference, I looked at some other posted questions on related topics, but they were just directing users to include the ntheorem.cwl file in the list of completions, but were not asking about syntax.
