Topic on Extension talk:VisualEditor

I am using MediaWiki 1.35, which comes with VisualEditor and CodeEditor extensions. Both are enabled in my LocalSettings.php:

wfLoadExtension( 'VisualEditor' );

wfLoadExtension( 'CodeEditor' );

However, in the "Insert" menu of my Visual Editor, I do not see the "Code block" option that I have experimented with on the Mediawiki sandbox page. How do I enable this? It would be very useful for our tech team support.

Code block uses the syntaxhighlight-tag, maybe you need the extension Extension:SyntaxHighlight first?
