Powershell and service fabric - how to select specific information and use it later actions?

Question

Below is code how I connect to my service fabric cluster and take needed application health information:

$ConnectArgs = @{
 ConnectionEndpoint = "mycluster:19000";  
 X509Credential = $True;  
 StoreLocation = 'CurrentUser';  
 StoreName = "MY"; 
 FindType = 'FindByThumbprint';  
 FindValue = "My_thumbprint"
 }
Connect-ServiceFabricCluster @ConnectArgs 
Get-ServiceFabricApplicationHealth -ApplicationName fabric:/Myapp -ExcludeHealthStatistics 

But currently there are lot of information, what I do not need. How to select just specific information from results? I need just ServiceHealthState information. I was able to exclude some information from application health, but didnt manage to exclude more.

UPDATE:

I found the following solution, which is close to what I try to achieve:

$health = Get-ServiceFabricApplicationHealth -ApplicationName "fabric:/Myapp" 
If ($health.AggregatedHealthState -eq "OK") {
    Write-Host "$($clusterApplication)'s health is ok!"
} Else {
    Write-Error "$($clusterApplication)'s health is not ok"
}

But I do not need to monitor AggregatedHealthState, because I am only interested in one part, which is under ServiceHealthStates, see example:

ApplicationName: fabric:/Myapp
AggregatedHealthState: Error
ServiceHealthStates:

ServiceName: fabric:/Myapp/Frontend
AggregatedHealthState: Error
ServiceName: fabric:/Myapp/Backend
AggregatedHealthState : Ok

But I dont know how to select this part, didnt find this from Google as well, hopefully someone could help.

Find solution what suits to me, post it here as well, if anyone else is facing against same question, my solution:

# Connect to Service Fabric cluster
$ConnectArgs = @{
 ConnectionEndpoint = "mycluster:19000";  
 X509Credential = $True;  
 StoreLocation = 'CurrentUser';  
 StoreName = "MY"; 
 FindType = 'FindByThumbprint';  
 FindValue = "My_Thumbprint"
 }
Connect-ServiceFabricCluster @ConnectArgs 

# Test Cluster connection
$Connection=Test-ServiceFabricClusterConnection
If ($Connection -eq "True") { 
    Write-Host "OK"}
Else 
{
    Write-Host "Connection to Service fabric cluster failed" 
}

# Service Fabric application health monotoring
$AppName="MyApp"

$AppHealth=Get-ServiceFabricApplicationHealth -ApplicationName $AppName 
$AppHealthBE=$AppHealth.ServiceHealthStates -match "Backend"

$node=Get-ServiceFabricApplicationHealth -ApplicationName $AppName
$nodetorestart=$node.DeployedApplicationHealthStates.NodeName -match  "MyNode"

If ($AppHealthBE.AggregatedHealthState -eq "Ok") {
   Write-Host "$($clusterApplication)/backend is OK"
   }
   Else
   {
   Write-Host "Need to perform restart on node: $nodetorestart)"
   #Restart-ServiceFabricNode -NodeName $nodetorestart
   }
