Do something if "Editable Text (Multi-Line)" is in focus?

I have an “Editable Text (Multi Line)” in my widget blueprint and I want the text to be deleted as soon as the player clicks on it for the first time because in the beginning, there is an example text written in it.

I cannot see an on focus event to be available in the editor, is there a way to do this?

Would having a button over the text that when clicked would set the text to blank then deactivate itself and then set the focus on the text input work?

Editable text have a function - has any user focus that returns true if player clicked on the text box.
If it is true set text to empty once.
