Thank you for your post and I apologize for the delayed response!
For your scenario of accessing Key Vault Secrets locally, I found an article that might help point you in the right direction - Configuring your local JS dev environment for Azure. Within this doc you'll be Working with Azure and the Azure SDK client libraries to Create environment variables for the Azure libraries.

Thank you for your time and patience throughout this issue.
