Cannot add plugin for Gsnap 32bit on Audacity 2.4.1

I am using a Mac with Mojave OS and I have the latest version of Audacity (2.4.1).
I have downloaded the Gsnap 32bit file but I can’t seem to add it to the plugins for Audacity.
I have tried copying and pasting the GSnap.dll file via the following methods:
And then closing Audacity and reopening it but when I select add/remove plugins under GENERATE or EFFECT or ANALYSE or TOOLS, I cannot see the Gsnap file as an option to add/enable.

Does anyone know how I can add the gsnap plugin to my audacity? I really want to autotune my singing tracks
Thank you!

Audacity is a 64-bit application and requires 64-bit plug-ins.

MacOS Catalina Version 10.15.7
Audacity 2.4.1

I am trying to install the GSnap plugin, downloaded from from .
I have unpacked the ZIP file, and copied the GSnap.vst file into the ~/Library/Audio/Plug-ins/VST folder
I restarted Audacity, and clicked on the menu item Effect>Add / Remove Plug-ins, which brought up a dialog box “Manage Plug-ins”.
I chose the “New” radio box, and found GSnap, selected it, and clicked on “Enable”, then OK.
Up comes a dialog box saying:

“GSnap.vst” cannot be opened because the developer cannot be verified.

macOS cannot verify that this app is free from malware.

How can I successfully install this plugin?

Thanks in advance for any help you can provide.
