How to upgrade npm in Laravel Sail ?

When I stop the vite live server sail npm run dev of Laravel by ctrl + c, the CLI tells me to upgrade npm with this message.

npm notice 
npm notice New patch version of npm available! 9.6.4 -> 9.6.5
npm notice Changelog: https://github.com/npm/cli/releases/tag/v9.6.5
npm notice Run npm install -g npm@9.6.5 to update!
npm notice
