rails6で、ログアウトボタンを押すと、routing errorになってしまう

前提・実現したいこと

railを勉強し始めて1か月の初心者です。メモアプリ的なものを作っているのですが、config/route.rbで、post "logout" => "users#logout"と設定しているはずなのに、routing errorの画面で、No route matches [GET] "/logout"と出てしまい、postとして受け取るはずが、getとして受け取ってしまっていてエラーが発生してしまっていることが起きているので、対処法を教えていただければ幸いです。

発生している問題・エラーメッセージ
