Customize sub-child-branches bubble style

[dcop7]

The main branch and first child-branch, the text is inside a bubble by default.
However, the next sub-branches are not.
How can I set the same style bubble to sub-child-branches?

You can freely shape the node with css as you like 😺

Do you have an example? I'm not an expert on CSS... Or at least point what to look

#map .map-container me-parent me-tpc {
  border-radius: 99px !important;
  border: var(--root-border-color) 2px solid;
  background-color: #fff;
  border-color: #dcdcdc;
  padding: 10px 20px;
}
