I have followed these directions on a fresh manual install (not composer) and got it all ‘installed’.
I ran the console command and it installed the plugin.
When I go to the plugins page I can see the plugin there
However I do not see it in the menu.
I have cleared the cache manually and with the console command.
I did have to add the patch (Fixing DoctrineEventSubscriber for plugin installations by escopecz · Pull Request #11206 · mautic/mautic · GitHub) in order to get it to install - which by the way fixed the install as the first time I did it I got the missing leads error.
These are the errors in the error log:
