Hook doesn't run when using custom configure transport

I have created a function to custom transport config and added it into module like that.
And I have logged the transport and I got a custom plugin added in here

However, after the email was sent successfully, I could not get a log and the email doesn't filter

Could you give it a look? Thank You!
