I upgraded to magento 2.3.3 but didn't noticed that they changed email classes and zend framework.
I am having a custom module for editing emails in magento admin.
But I am having error:
FastCGI sent in stderr: "PHP message: PHP Fatal error: Uncaught Error: Class 'Zend_Reflection_Class' not found in myfile.php
My code is:

This is happening also with another class:
Zend_Reflection_Method
Anyone can help how can I declare these classes now please?
