How can I set ENVIRONMENT status in Azure DevOps yaml pipeline

Question

I am creating a CICD pipeline in Azure DevOps. I have a pipeline that has a name set dynamically.

name: 'Set dynamically below in a task' 

Then in BUILD stage I update it

[string] $date = (Get-Date -Format 'yyyyMMdd')
[string] $projectVersion = (Get-Content 'version.json') -join "`n" | ConvertFrom-Json | Select -ExpandProperty "version"      
[string] $buildName = "$projectVersion.$(Build.BuildId)+$date.API"     
Write-Host "##vso[build.updatebuildnumber]$buildName"

I have currently 3 stages

1. Build
   • builds up
   • set build name via VSO command
   • publish artifact
2. Deploy to DEV
   • download artifact and deploy to the dev environment
3. Deploy to TEST
   • download artifact and deploy to test environment

I am actually using ENVIRONMENT within Azure DevOps to track all deployments and here is the problem. While pipeline build number is updated properly in Pipelines view

when I go to Environments tab the not so updated build name is being displayed.

How can I change that?
