Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch react-country-region-selector@3.6.1 for the project I'm working on.

Here is the diff that solved my problem:

diff --git a/node_modules/react-country-region-selector/dist/rcrs.es.js b/node_modules/react-country-region-selector/dist/rcrs.es.js
