Custom labels

[brootle]

Based on this I see it's easy to add labels on edges https://reaflow.dev/?path=/story/demos-edges--labels

But what if I want label to have green background and red border and font size 12 for example? I see that nodes can be dramatically modified using foreignobject as described here https://reaflow.dev/?path=/story/demos-nodes--foreign-objects

Is there anything I can do to turn my label into div element attaching my own style? And I would like to have more control on label position as well. Closer to the start or closer to the end. See how this can be achieved with ReactFlow for example https://reactflow.dev/docs/examples/edges/edge-label-renderer/

Maybe I am missing something obvious?
