PowerShell Start-Process with other user credential and wait

I am starting a process with PowerShell using another user with elevated rights.

$username = "username" 
$password = "password"
$startWithElevatedRights = "notepad"

$credentials = New-Object System.Management.Automation.PSCredential -ArgumentList @($username,(ConvertTo-SecureString -String $password -AsPlainText -Force))
Start-Process powershell -Credential $credentials -ArgumentList '-noprofile -command &{Start-Process ‘,  $startWithElevatedRights, ‘ -Wait -verb runas}'

I know it's bad style to write user credentials to code, but it is used within full automated procedures, so this is necessary. My problem is, that I cannot wait until the process (last code line) finished. The inner process waits as expected.

I tried the parameter -Wait, * | Wait-Process, * | Out-Null, with return Value (which is always null) Nothing works.

Is there any solution waiting until the process has exited? If there is any solution for PowerShell 2.0 it would be the best for my use case.

You can get Process object from Start-Process using PassThru parameter and then wait for it to exit.

$username = "username" 
$password = "password"
$startWithElevatedRights = "notepad"

$credentials = New-Object System.Management.Automation.PSCredential -ArgumentList @($username,(ConvertTo-SecureString -String $password -AsPlainText -Force))
$ps = Start-Process -PassThru -FilePath powershell -Credential $credentials -ArgumentList '-noprofile -command &{Start-Process ',  $startWithElevatedRights, ' -Wait -verb runas}'

$ps.WaitForExit()
