Reduce size importing moment.js

I followed the suggestions reported here to reduce my Vue.JS SAP bundle size, and in details, importing moment as:

import moment from 'moment/src/moment'

or even better with an alias set within "configureWebpack" section of "vue.config.js", but in doing so I receive the following error when running npm run build or npm run serve:

Can't resolve './locale' in '/path_folder_project/node_modules/moment/src/lib/locale'

I was not able to resolve it, any suggestion? The installed moment.js module is @2.29.1.
