Azure DevOps configure code coverage with JaCoCo

I want to view code coverage in Azure DevOps.

So I configured my azure-pipelines.yml like this:

trigger:
- master

pool:
  vmImage: 'windows-latest'

variables:
  solution: '**/*.sln'
  buildPlatform: 'Any CPU'
  buildConfiguration: 'Release'

steps:
- task: NuGetToolInstaller@1

- task: NuGetCommand@2
  inputs:
    restoreSolution: '$(solution)'

- task: VSBuild@1
  inputs:
    solution: '$(solution)'
    msbuildArgs: '/p:DeployOnBuild=true /p:WebPublishMethod=Package /p:PackageAsSingleFile=true /p:SkipInvalidConfigurations=true /p:DesktopBuildPackageLocation="$(build.artifactStagingDirectory)\WebApp.zip" /p:DeployIisAppPath="Default Web Site" /p:CollectCoverage=true /p:CoverletOutputFormat=jacoco /p:CoverletOutput=$(Build.DefaultWorkingDirectory)/TestResults/Coverage/'''
    platform: '$(buildPlatform)'
    configuration: '$(buildConfiguration)'
    maximumCpuCount: true

- task: VSTest@2
  inputs:
    testSelector: 'testAssemblies'
    testAssemblyVer2: |
      **\*test.dll
      !**\*TestAdapter.dll
      !**\obj\**
    searchFolder: '$(System.DefaultWorkingDirectory)'
    codeCoverageEnabled: true
    platform: '$(buildPlatform)'
    configuration: '$(buildConfiguration)'

- task: PublishCodeCoverageResults@1
  inputs:
    codeCoverageTool: 'JaCoCo'
    summaryFileLocation: '$(System.DefaultWorkingDirectory)/TestResults/Coverage/*.xml'

and the nuget-package coverlet.collector was added by Azure DevOps checkin. I also added the part /p:CollectCoverage=true /p:CoverletOutputFormat=jacoco /p:CoverletOutput=$(Build.DefaultWorkingDirectory)/TestResults/Coverage/ in step VSBuild.

However, when I click on the last run pipeline it only shows a button Download code coverage results with a link to a .coverage-file.

I decided for JaCoCo over Cobertura for no specific reason, so taht can be changed if necessary.

How can I view code coverage?
