AppleScript - Iterate all open applications / process and execute a menu command

I am trying to write an AppleScript to be triggered by hotkey in Keyboard Maestro on MacOS

What I want to do, and please do not suggest ANYTHING ELSE, such as hide all, or hide functionality. I am looking for minimize all open windows functionality, including the animation.

I can already do hide all.

So what I want to do is iterate all open windows, and trigger the menu option Window -> Minimize or if possible trigger minimize in a different manner.

Here is what I have so far but it is not fully working, only partially:

tell application "System Events"
    set currentProcesses to name of every application process whose visible = true
end tell

repeat with tmpProcess in currentProcesses

    tell application "System Events" to tell process tmpProcess

        set frontmost to true
        ---activate

        tell menu bar item "Window" of menu bar 1
            click menu item "Minimize" of menu 1
        end tell

    end tell

    delay 1

end repeat

Note, some applications will have a Minimise without a z for Minimize. . Would be good if the solution triggered some global minimize action rather than go through the menu system.

Another working example, best so far.

tell application "System Events"
    set currentProcesses to name of every application process whose visible = true
end tell

repeat with tmpProcess in currentProcesses

    tell application "System Events" to tell process tmpProcess
        set frontmost to true

        try
            tell menu bar item "Window" of menu bar 1

                try
                    click menu item "Minimize" of menu 1
                on error
                    try
                        click menu item "Minimise" of menu 1
                    end try
                end try

            end tell

        end try

        delay 0.1

        set visible to false

    end tell


end repeat
