What's the best way to return to a previous role in AWS? I am running a pulumi script with this in the yaml config

aws:assumeRole:
    roleArn: arn:aws:iam:...

However this role can't manage certain resources. I want to setup a new provider that uses my original privileged role to manage those resources. What's the best way to do that?

aws:assumeRole

will be the default provider. If you explicitly create another provider, you can set `assumeRole`:

const awsProvider = new aws.Provider("explicit-provider", {
    assumeRole: {
        roleArn: "your-role-arn"
    },
})
