How to remove a sketch in p5.js IDE

I am new in using p5.js environment.
I wrote a few sketches and I need to remove part of them. How do I remove a sketch?


A few hours later, I found the following solution:
On the sketch page, top left, if we click the author name we get a new page where the number of sketches is mentioned.
Clicking this number opens a list of sketches (a sort of directory in another style)… If we move the mouse on the desired sketch we can see a vertical pattern of 3 dots at the top left of the sketch. If we click this pattern we can select the cross X to delete this sketch.
