Question Help with SpriteShape Corners

Hello

I need help to set up a SpriteShape profile that will allow me to have fixed circles on corners. The corners's cirlces should be a little bigger than the line between them, so that I have a structure with lines and points.

In the GIF I attached to this post there is an example of what is happening.

How can I make a profile where the corners will be always a normal circle without changing?

Thank you.
