I'm trying to figure out if this is feasible.

Ideally, I'd like to set the [HTML elements](https://github.com/iOnline247/node-red-contrib-aws-any/blob/EnvCredentialSupport/src/nodes/aws-sdk-any-config/template.html#L39-L48) to be readonly (and style with CSS, so it's apparent), if the credentials are [supplied via environment variables](https://github.com/iOnline247/node-red-contrib-aws-any/blob/EnvCredentialSupport/src/nodes/aws-sdk-any-config/aws-sdk-any-config.js). I **am** able to set the environment variables and make the API calls after saving blank values within the config node.

When I hit [this breakpoint](https://github.com/iOnline247/node-red-contrib-aws-any/blob/EnvCredentialSupport/src/nodes/aws-sdk-any-config/script.js#L14), I doesn't appear I'm able to discern if the credentials have been set and the `input`'s are blank. Is there a way to tell or signal the UI that these were set already, so the UX isn't clunky?

For context, this is how the AWS SDK looks for credentials:
