Notarize Lrdevplugin MAC OS BigSur 11.0. : Help or Manual needed

Here's an article on how to notarize command-line executables:

It's more than a little tedious to set up. However, you don't need to notarize the executable -- instead, the Init can remove the com.apple.quarantine extended attrribute from the executable.  Here's what several of my plugins do:

--[[----------------------------------------------------------------------------
public boolean unquarantinePlugin ()

On Mac, if the file "_quarantined" exists in the current plugin's folder,
removes the "com.apple.quarantine" extended attribute from all files in the
folder and removes the "_quarantined" file. Returns true if successful.
Returns false if there's any sort of error, displaying an error message to the
user, and leaving the "_quarantined" file in place.

On Windows, always returns true.

function Util.unquarantinePlugin ()
    if WIN_ENV then return true end

    local path = child (_PLUGIN.path, "_quarantined")
    if not LrFileUtils.exists (path) then return true end

    local code, err = Util.safeExecute (
        "xattr -r -d com.apple.quarantine '" .. _PLUGIN.path .. "'", true)
    if code ~= 0 then 
        Debug.logn ("xattr: ", code, err)
        LrDialogs.message ("Problem unquarantining the plugin after download", 
            "See 'debug.log' for details. The plugin may not run correctly " ..
                " -- contact support via the Help page")
        return false
        end

    LrFileUtils.delete (path)
    return true
    end
