aws-mfa hitting to "https://sts.amazonaws.com/" instead of "https://sts.<region>.amazonaws.com/"

I am using aws-mfa.

When i run aws-mfa with profile name with long-term credentials in my ~/.aws/credentials, it is always reaching to
https://sts.amazonaws.com as my machine is in private network so not able to resolve it and failing to have temporary creds in my file.

You have to create an environment variable with the following: AWS_STS_REGIONAL_ENDPOINTS='regional'

Hi, even after adding this it is still going to the global endpoint instead of REGIONAL. If i remember correctly I tried this earlier as well.

Adding "sts_regional_endpoints = regional" in ~/.aws/config file, worked but will it should not be created by aws-mfa?
because what we create profile is default-long-term.
