PowerShell, Windows Terminal size and position manipulation

Question

I use some functions (below) in my $Profile to move and resize my PowerShell consoles. These work very nicely. I would like to use Windows Terminal more but I would also like to have these types of operations work there and presumably there must be some techniques to manipulate these windows (either PowerShell or accessing .NET functions).

How can I achieve similar results to the below within Windows Terminal sessions?

Note that this question is specifically about manipulation of the new Windows Terminal and not the PowerShell console (where the below work fine). The new Windows Terminal from Microsoft is here

Here's my code:

function Global:Set-ConsolePosition ($x, $y, $w, $h) {
    # Note: the DLL code below should not be indented from the left-side
    Add-Type -Name Window -Namespace Console -MemberDefinition '
[DllImport("Kernel32.dll")] 
public static extern IntPtr GetConsoleWindow();
[DllImport("user32.dll")]
public static extern bool MoveWindow(IntPtr hWnd, int X, int Y, int W, int H); '
    # Do the Add-Type outside of the function as repeating it in a session can cause errors
    $consoleHWND = [Console.Window]::GetConsoleWindow();
    $consoleHWND = [Console.Window]::MoveWindow($consoleHWND, $x, $y, $w, $h);
    # $consoleHWND = [Console.Window]::MoveWindow($consoleHWND,75,0,600,600);
    # $consoleHWND = [Console.Window]::MoveWindow($consoleHWND,-6,0,600,600);
}
function lll {
    Add-Type -AssemblyName System.Windows.Forms
    $Screen = [System.Windows.Forms.Screen]::PrimaryScreen
    $width = $Screen.WorkingArea.Width   # .WorkingArea ignores the taskbar, .Bounds is whole screen
    $height = $Screen.WorkingArea.Height
    $w = $width/2 + 13
    $h = $height + 8
    $x = -7
    $y = 0
    Set-ConsolePosition $x $y $w $h

    $MyBuffer = $Host.UI.RawUI.BufferSize
    $MyWindow = $Host.UI.RawUI.WindowSize
    $MyBuffer.Height = 9999
    "`nWindowSize $($MyWindow.Width)x$($MyWindow.Height) (Buffer $($MyBuffer.Width)x$($MyBuffer.Height))"
    "Position : Left:$x Top:$y Width:$w Height:$h`n"
}
function rrr {
    Add-Type -AssemblyName System.Windows.Forms
    $Screen = [System.Windows.Forms.Screen]::PrimaryScreen
    $width = $Screen.WorkingArea.Width   # .WorkingArea ignores the taskbar, .Bounds is whole screen
    $height = $Screen.WorkingArea.Height
    $w = $width/2 + 13
    $h = $height + 8
    $x = $w - 20
    $y = 0
    Set-ConsolePosition $x $y $w $h

    $MyBuffer = $Host.UI.RawUI.BufferSize
    $MyWindow = $Host.UI.RawUI.WindowSize
    $MyBuffer.Height = 9999
    "`nWindowSize $($MyWindow.Width)x$($MyWindow.Height) (Buffer $($MyBuffer.Width)x$($MyBuffer.Height))"
    "Position : Left:$x Top:$y Width:$w Height:$h`n"
}
function fff {
    Set-ConsolePosition -7 0 600 600
    if ($Host.Name -match "console") {
        $MaxHeight = $host.UI.RawUI.MaxPhysicalWindowSize.Height - 1
        $MaxWidth = $host.UI.RawUI.MaxPhysicalWindowSize.Width
        $MyBuffer = $Host.UI.RawUI.BufferSize
        $MyWindow = $Host.UI.RawUI.WindowSize
        $MyWindow.Height = $MaxHeight
        $MyWindow.Width = $Maxwidth
        $MyBuffer.Height = 9999
        $MyBuffer.Width = $Maxwidth
        # $host.UI.RawUI.set_bufferSize($MyBuffer)
        # $host.UI.RawUI.set_windowSize($MyWindow)
        $host.UI.RawUI.BufferSize = $MyBuffer
        $host.UI.RawUI.WindowSize = $MyWindow
        "`nWindowSize $($MyWindow.Width)x$($MyWindow.Height) (Buffer $($MyBuffer.Width)x$($MyBuffer.Height))`n"
    }
