리사이클러뷰는 snake_case로 선언하시고 여기서는 camelCase를 사용하셨는데, 이렇게 통일하지 않고 사용하시면 코드의 가독성이 떨어질 수 있어요. 웬만해서는 네이밍 컨벤션 통일해주세요!

recyclerview의 아이템 변동 사항이 없다면 MutableList 보단 불변 List를 사용하는 게 좋습니다!
불변성을 보장해 데이터 무결성을 유지할 수 있어용

매니패스트에 FOREGROUND_SERVICE라는 권한을 추가해야 한다고 하여 권한 확인하는 부분에 해당 권한을 허용하도록 함.
그런데 권한 허용 창이 뜨지 않길래 찾아보니 매니패스트에만 명시하면 되는 작업이라 함.
그래서 FOREGROUND_SERVICE권한 허용 코드가 있지만, 사용하지는 않음(다시 코드 수정하기 귀찮아서;; 어짜피 오류도 안나고)
