React development with multiple .env files

Question

I have a ReactJs application that was created using Create-React-App and I am looking for an option to work with multiple .env files with custom environment variables for various environments, like env.local, env.qa, env.development, env.stage, and env.production. I understand how to use env-cmd (which seems like the widely suggested solution for my case). However, it has not been updated in a long while and I am not too certain if that is an ideal choice for my case now. Can anyone please suggest an alternative or advise on this regard? Thank you.
