Loading AWS JavaScript SDK V3 Credentials From A JSON File

• Doesn't look like you can load directly from a JSON like you could in V2.
• It lists it here as an option, but can't find where to actually do it: https://docs.aws.amazon.com/sdk-for-javascript/v3/developer-guide/setting-credentials-node.html
• There is a way to load from an external process.
• That's probably the way to do it.
• Check this out and figure out a way to set it up: https://docs.aws.amazon.com/sdk-for-javascript/v3/developer-guide/loading-node-credentials-configured-credential-process.html

For reference, here's the note from V2 - https://docs.aws.amazon.com/sdk-for-javascript/v2/developer-guide/loading-node-credentials-json-file.html
