If you want to render a custom component for connection lines, you can set the connectionLineComponent prop on the <ReactFlow /> component. The ConnectionLineComponentProps are passed to your custom component.

export type ConnectionLineComponentProps = {
  connectionLineStyle?: React.CSSProperties;
  connectionLineType: ConnectionLineType;
  fromNode?: Node;
  fromHandle?: Handle;
  fromX: number;
  fromY: number;
  toX: number;
  toY: number;
  fromPosition: Position;
  toPosition: Position;
  connectionStatus: 'valid' | 'invalid' | null;
};
