Hi,
Based on my search, there isn't an "officially sanctioned" way to do this because by design users who have access to RemoteApp will have Remote Desktop access because same permissions apply to both services, actually both services are mostly the same. When a user starts a RemoteApp he is actually loggin on to the server, but can only see the application, and not the rest of the desktop.
But you could do something silly like use Group Policy to set the user's shell to be "logoff.exe" such that if they attempted to access the machine's desktop they'd be immediately logged-off.
Please refer to the information below:

Hope this helps and please help to accept as Answer if the response is useful.

Hi,

I create a logon script that verify current user processes finding by explorer, that run only on remote desktop connections. If explorer match, I get user groups on AD and check if it belongs to a specific group, create for this purpose, so i exit script or call the logoff.exe closing this session.

The script

$processes = Get-Process | ? {$_.SI -eq (Get-Process -PID $PID).SessionId}

foreach($p in $processes){
    
    if($p -like '*explorer*'){

        Write-Output 'Remote Desktop'
        
        $token = [System.Security.Principal.WindowsIdentity]::GetCurrent() 
        ForEach($group in $token.Groups){
            $groupName = $group.Translate([System.Security.Principal.NTAccount])
            if($groupName -like "*Specific_group"){
                Write-Host "You are authorized"
                exit
            }
        }

        Write-Host "You are unauthorized"
        & "C:\Windows\System32\logoff.exe"
    }
}

Write-Output 'Remote App'
