Missing parameter 'id' in actions.list()

Hello, I am refactoring a javascript project to typescript and found out actions.list() doesn't support parameter 'id' even though it is being used as the output is filtered.

https://github.com/apache/openwhisk-client-js/blob/1aba396e8a59afd5a90acb8157f2009746d7a714/lib/main.d.ts#L60-L61

I'm not sure if the type of id is only optional string or something else. Thank you
