Hoovering button effect

Hello, i have tested how to achieve specific effect on a button in my page and have installed Unlimited Elements and Widget – Content Box Hover Text Reveal. Maybe, its not the right widget for that….
I have an elementor block with picture background for a “cover homescreen”.
Want to put button, with multiple lines text in the lower left side, with a hovering effect that show additional line of text. Thats why i used “Content Box Hover Text Reveal”.
The problem is that i wanna the whole “box” to be clickable and not only the button.
I have tried to edit the widget css but without success.
Is there some way to achieve it or some other better decision?
Previously have tried button element and Creative button from Essentila addons.
The same topic is in “Fixing wordpress” forum, didnt see option to move it here.

Hope someone can help me here, Thanks!
