AWS CodeBuild Code Coverage supporting clover.xml

I am using CDK to deploy a CodePipeline which then handles cross account deployments for my NodeJS Lambda. In the build stage of my CodePipeline, I would like to run unit tests and generate a code coverage report. I am using jest with the coverage flag which default creates a clover.xml for code coverage.

https://docs.aws.amazon.com/codebuild/latest/userguide/code-coverage-report.html says it supports clover.xml but I have been struggling to find a good example on how to do this, when I try to deploy my cdk pipeline stack with reports like this

          reports: {
            jest_reports: {
              files: ['reports/CodeCoverageReport.xml'],
              fileFormat: 'JUNITXML',
              baseDirectory: 'reports',
            },
            clover_reports: {
                files: ['reports/coverage/jest/clover.xml'],
                fileFormat: 'CLOVERXML',
                baseDirectory: 'reports',
            },
          },

I am getting this error:

[code_coverage_reports: [error processing report: [/codebuild/output/src245295669/src/reports/coverage/jest/clover.xml: expected element type <testsuite> but have <coverage>]]]

Is there any examples on how to do this or any advice on how to fix this?

Commenting the fix here for visibility in case anyone else runs into this. What happens is the incorrect version in my original post created the report group clover_reports as a TEST report type. This is because the keys were incorrect and the default is JUNITXML. The code snippet here: https://github.com/aws/aws-cdk/issues/13867#issuecomment-810555222 is correct, all I had to do was delete the incorrectly created report group. Alternatively, one could simply rename the report group to something else.
