AWS Bedrock Right pb when testing prompt flow

Hello.

When I set up a prompt flow in my AWS account and checked the automatically created IAM role, the following IAM policy was attached.
Therefore, I think it is necessary to configure the IAM role to at least allow "bedrock:GetFlow" and "bedrock:InvokeModel".

    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "bedrock:GetFlow",
            "Resource": [
                "arn:aws:bedrock:us-east-1:111111111111:flow/YYYYYYYYYY"
            ]
        }
    ]
}

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "bedrock:InvokeModel",
            "Resource": [
                "arn:aws:bedrock:us-east-1::foundation-model/amazon.titan-text-premier-v1:0"
            ]
        }
    ]
}
