Metricbeat AWS Module - billing metricset

This config results in a empty metricbeat-7.10.0-2021.02.10-000001 index with 0 documents.

This points to a lack of user permissions for my account, although my AWS Admin told me, that I have the following permissions:

ec2:DescribeInstances
ec2:DescribeRegions
cloudwatch:GetMetricData
cloudwatch:ListMetrics
sts:GetCallerIdentity
iam:ListAccountAliases
tag:getResources
sts:GetCallerIdentity
ce:GetCostAndUsage

which should sufice according to the AWS Module docu.

But in the Cloudwatch Portal I only see the metrics for:

Services: CloudWatch, Resource: ListMetrics, Type: API, Class: None, Metric name: CallCount

Services: CloudWatch, Resource: DescribeAlarm, Type: API, Class: None, Metric name: CallCount
