Does the Lezer grammar syntax support comments?

I’d like to document my grammar(s) and add explicit code-folding instructions to vim for certain regions, but I don’t see the syntax of lezer defined anywhere?

Is there a lezer grammar for lezer?

Update!

I found lezer-grammar/lezer.grammar at main · lezer-parser/lezer-grammar · GitHub

it uses JavaScript / C / C# / etc style comments: lezer-grammar/lezer.grammar at main · lezer-parser/lezer-grammar · GitHub
