Can we provide temporary access key,ID and session token in AWS Credentials File

Hello.

I hope the steps in the document below will be helpful.
The steps in the document below use "aws sts assume-role" to obtain temporary credentials from an IAM role.
Rather than creating an authentication file, it is registered in an environment variable.

Hello,

The official documentation states that storing temporary credentials in credential files is acceptable [1]. However, instead of updating the file each time the short-term credentials expire, consider exporting them as environment variables [2]. This avoids repeatedly editing the credential file.
