Where do event handlers work other than init.php?

Question

Hello, I am developing a ready-made solution and a part of the functionality based on event handlers (tracking the creation of an infoblock element). At the moment, the handler code is located in init.php, since it is forbidden to change user files when unpacking the solution, where to place the event handler code?

Answer 1

Write your own module that will be installed when the solution is installed and subscribe to the necessary events. And in it already place handlers where you want.
