Description
To complement the original no-unused-private-class-members rule which works with typescript but doesn't detect the private keyword:
Private class members that are declared and not used anywhere in the code are most likely an error due to incomplete refactoring. Such class members take up space in the code and can lead to confusion by readers.
— From: https://eslint.org/docs/rules/no-unused-private-class-members#no-unused-private-class-members
