Draw connections without head

Hello,

I would like to be able to render connections without a head - as a line so to say.
Like this:

Currently I am coloring my flows as custom entry in the Replace Menu like this:

export function getEntries(element, modeling) {
  return {
    black: {
      className: 'bpmn-icon-connection-black',
      label: 'Black Flow',
      action: () => {
        modeling.setColor(element, {stroke: 'black'});
      }
    },
    yellow: {
      className: 'bpmn-icon-connection-yellow',
      label: 'Yellow Flow',
      action: () => {
        modeling.setColor(element, {stroke: '#ffb300', fill: 'white'});
      }
    }
  }
}

I tried to change the color of “fill” to “none” or “white” but it seems like that’s the wrong attribute as nothing changes.
Can you tell me what attribute I can use to color the tip of the connection arrow or if there is a way to completely remove it?

Thanks in advance!

The connection you mention is a sequence flow, and it is directed by design? Do you seek to introduce a custom connection type?

Render customizations typically take place in the form of a custom renderer.

Yes, I want to introduce a custom connection type.

I already have a custom renderer but I only use it for custom tasks and the like by replacing the svg.
However, I am not sure how to do this for a connection as I can’t simply replace the svg of it because it would still be directed, right?
Could you possibly tell me how to do this?

Thanks in advance!
