Citrix Get-Brokerapplication from specific server - powershell

Question

On XenApp 6.x servers, there was a cmdlet like this:
GET-XAApplication -ServerName servername
I used to open a PSSession on the adminserver, then got all servers with GET-XAServer and then I simply did the Application command in a foreach loop, where the ServerName parameter was the servername from XAServer. Now I want to do the same on Version 7, but I can't figure out how it works.
I installed all new cmdlets for the newer Version. I found out I can get the Applications with GET-Brokerapplication - but I can't pass a parameter to tell the command from which server I want to grab them, so I can only grab them from my admin server.
Maybe someone can help me? I've already looked at the documentation (https://docs.citrix.com/de-de/xenapp-and-xendesktop/7-6/cds-sdk-wrapper-rho/xad-commands/citrix-broker-admin-v2-wrapper-xd76/get-brokerapplication-xd76.html) but I can't find a parameter who allows me to do what I want. MaybeI'm looking at the wrong cmdlet?
I would be really happy if someone has a advise for me.

In XenApp 6.x there were Worker Groups and you should have been publishing applications for Worker Groups instead of individual servers. Then you can enumerate Worker Groups and Applications:
$wgs = Get-XAWorkerGroup
foreach ($group in $wgs) {
$apps = Get-XAApplication -WorkerGroupName $group
}
In XenApp 7.x WorkerGroups are replaced by Delivery Groups and you can enumerate them and associated applications:
$groups = Get-BrokerDesktopGroup
foreach ($group in $groups) {
$apps = Get-BrokerApplication -AssociatedDesktopGroupUid $group.UID
}
