Export from Lightroom Plugin

I’m on aa Apple Mac and I would like to have a copy of the Lightroom plugin that exports raw files from Lightroom to PhotoLab4.

I am unable to find the plugin on the website and suspect that it gets installed automatically if Lightroom is installed. I no longer have Lightroom so can not confirm this and wonder if any users of PL4 and Lightroom can confirm that a plugin exists.

The reason I’m asking is that I use a third party image management application called NeoFinder to manage my images. I use some shell code found in the Lightroom Plugin to pass raw files from NeoFinder into PhotoLab3. The component I am interested in is named “PhotoLabLauncher” and I suspect it is updated with each update of PhotoLab as I have not been able to get the version that works with PL3 to work properly with PL4.

best wishes
