SpamSieve Plugin not appearing in Mail preferences

When opening Mail this morning, I was surprised o have the alert from SpamSieve saying that the plugin was disabled. Thus, I reinstalled the plugin according to SpamSieve instructions and when verifying in Mail, the plugin list is still empty :frowning:
My configuration is macOS Monterey version 12.4 (21F79) Mail Version 16.0 (3696.100.31)

Please see If the Apple Mail Plug-In Doesn’t Appear in the List or Doesn’t Stay Enabled.

Thanks for your answer.
In fact I’m a kind of stupid guy: I was not looking for the plug-in with the Manage Plug-ins… button where the plugin is actually listed and checked and SpamSieve works fine.
Sorry :worried:
