TFS 2017 Change Release summary description during build - tfs

Question

We're using Team Foundation Server 2017. After lots of releasedefinition-making, I'm stucking on a problem.
During the release, I receive a message which I would write directly into the release description summary. I checked for an such an activity in the Marketstore, but I haven't found one.
Am I not able to search for the right activity or is there another way for updating this?

Currently, you can only update release name with Logging command, which requires agent version 2.132+. So the only way to update the release description is adding a powershell script in your release definition. The script is as below:
param (
[Parameter(Mandatory=$true)]
[ValidateNotNullOrEmpty()]
[string] $token
)
## Construct a basic auth head using PAT
function BasicAuthHeader()
{
param([string]$authtoken)
$ba = (":{0}" -f $authtoken)
$ba = [System.Text.Encoding]::UTF8.GetBytes($ba)
$ba = [System.Convert]::ToBase64String($ba)
$h = #{Authorization=("Basic{0}" -f $ba);ContentType="application/json"}
return $h
}
$getReleaseUri = "http://TFS2017:8080/tfs/DefaultCollection/TeamProject/_apis/release/releases/$($env:RELEASE_RELEASEID)?api-version=3.2-preview"
$h = BasicAuthHeader $token
$release = Invoke-RestMethod -Uri $getReleaseUri -Headers $h -Method Get
# Update an existing variable named d1 to its new value d5
$release.description = "this is a test";
####****************** update the modified object **************************
$release2 = $release | ConvertTo-Json -Depth 100
$release2 = [Text.Encoding]::UTF8.GetBytes($release2)
$updateReleaseUri = "http://TFS2017:8080/tfs/DefaultCollection/TeamProject/_apis/release/releases/$($env:Release_ReleaseId)?api-version=3.2-preview"
$content2 = Invoke-RestMethod -Uri $updateReleaseUri -Method Put -Headers $h -ContentType “application/json” -Body $release2 -Verbose -Debug
write-host "=========================================================="
And with argument -token {PAT}. Check my screenshot below:
I've tested on my side, it can update release description successfully.
