Hi there, thanks so much for the recent updates to the instructions for getting this plugin to work on Mojave. However, even when I follow the instructions, no button shows up in the General preferences of Mail for me to allow/enable this extension. I'm not sure what I'm doing wrong, but I've build the plugin with Xcode, copied the folder form the tmp dir to the mail library dir as instructed, but when I re-start mail, that manage plugins button just isn't there. Any thoughts?
Thanks!
