How to replace a lambda with a method reference-CodePudding

I am getting this warning on SonarQube: "Replace this lambda with a method reference."

The code is :

childrenNames = StreamSupport.stream(favouritesFolder.getChildren().spliterator(), false)
    .map(node -> node.getName())
    .limit(NUMBER_OF_FILES_TO_DISPLAY)
    .collect(Collectors.toList());

How can I replace the lambda with a method reference in my case?

I was able to solve the issue by assigning the type of the node which is in my case CmisObject as following:

childrenNames = StreamSupport.stream(favouritesFolder.getChildren().spliterator(), false)
    .map(CmisObject::getName)
    .limit(NUMBER_OF_FILES_TO_DISPLAY)
    .collect(Collectors.toList());

node -> node.getName()=>Node::getName
