How do I add the AWS account into the Splunk AWS add-on using IAM role?

[sivagct]

Hello

I have installed the Splunk add on for AWS on our on perm Splunk instance. Using IAM User is not allowed in our company due to security policy. We can only use IAM role to access the resources. In Splunk aws addon page, Under configuration tab, Adding AWS account in Splunk requires KeyID/secret key which I can not create due to my company policy.. Is there a way to connect to the AWS account using IAM role that has the Splunk inline policy attached to it?

Thanks in advance.
