How to get a gap in a circle in draw.io?

I am trying to create a small gap inside a circle I have created in draw.io but I do not see not even an eraser than I can just erase that area:

Is there a way I could do it here:

ellipse;whiteSpace=wrap;html=1;aspect=fixed;shadow=0;strokeWidth=11;perimeterSpacing=0;spacingRight=1;
