Removing “Written by” but keep author name [closed]

I am trying to remove the "Written by" text at the bottom of my posts on wordpress.com, but I want to keep the author’s name

enter image description here

Is there a way to do so? So far I was trying to use the HTML classes for the Written by <author_name> line to hide the line, but they both share the same classes. Is there a workaround?

Thank you!
