Even though there isn't a command being invoked here, the message should still propagate through discord. Or else it might mask issues in the future.

The documentation says that its the equivalent of those two calls, plus we need to know whether or not a command exists before we log an internal message.

@kyb3r I mean add it at the end of on_message, that "suggested change" section might be a bit misleading. So...

...
thread = await self.threads.find(channel=ctx.channel)
if thread is not None:
    await self.modmail_api.append_log(message, type='internal')
return await self.process_commands(message)

But we are not logging command messages

Yeah I know we're not logging commands, but we should still include return await self.invoke(ctx) at the end. This way "command_error" event will still be dispatched when an invalid command was received.

It doesn't really matter right now, but it may cause problems later as this suppresses the CommandNotFound from on_command_error.

Btw, also change:

if ctx.command:

to:

if ctx.command is not None:
