New new topic: providers and invoke calls. I'm not getting the expected caller ID back from this:

const provider = new aws.Provider('x", { region: 'us-east-1', profile: 'assumed-role-in-acct-FOO'});
const identity = aws.getCallerIdentity({ provider: provider});

The returned

identity

is the one from the default provider. I expect to see a different arn, accountId and userId in there. Am I doing something wrong?
