Problem with action mapping

Summarizing my problem well, I need a single button (right mouse button) to do two things.

In my project (TopDown) I defined that instead of the left mouse button, the character moves with the right mouse button.

I happen to like that when I click the right mouse button on a particular actor, a simple event is called (print hello).

I tried doing this with the Event On Clicked, but it only works with the left mouse button:

With the help of these links:

I figured out how to do an action/event call with the right mouse button, but even then I did not succeed.

Soon I discovered that the reason was that there was already an action that was executed with the right mouse button (walk/set destination):

I would like my character to continue to move with the right click of the mouse, but how do I also call an event when I click the right mouse button?
