Best Practice introduced by
It is generally recommended to explicitly declare the visibility for methods.

Adding explicit visibility (private, protected, or public) is generally recommend to communicate to other developers how, and from where this method is intended to be used.

Unused Code introduced by
The parameter $request is not used and could be removed. ( Ignorable by Annotation )

If this is a false-positive, you can also ignore this issue in your code via the ignore-unused  annotation
