comment/uncomment feature in vscode DSL plugin

[goto40]

This is somehow only loosely related to langium - but I wonder how I could add/enable the "Toogle Line Comment" feature for my langium vscode plugin of my langium DSL. Probably this just a standard vscode plugin configuration.

Is there already an example? It does not seem to be in the plugin for *.langium files (at least the version I installed).
If not I will find out myself...

The langium DSL/plugin has the feature. I will look it up there.

FYI, the behavior can the achieved through this language configuration.
