[Helm] Using the chart can I configure Cloudwatch dasource via role?

Guys,

I’m using the Kube Prometheus Stack and the Grafana Helm Chart is part of them such as sub-chart.

I need to configure the AWS Cloudwatch datasource, but I didn’t want to use access and secret keys. So, using the chart, is it possible to configure it to use an IAM Role?

If yes, what is the way to configure it?

I already have the role created with permissions to read the AWS logs.

I’m not sure, but would be this configs?
