Hi, how do I change the color of a lifeline that was created using _evt("foo", "enable")?

Is it maybe possible to create it invisibly using _seq so I can set the lifeline style?

It looks like lifeline style is not exposed as a parameter of _evt
As a workaround, you can directly write the full element like so:

#chronos.diagram({
  import chronos: *

  ((
    type: "evt",
    participant: "a",
    event: "enable",
    lifeline-style: (fill: red)
  ),)
  
  _seq("a", "b")

  _seq("b", "a", disable-dst: true)
})
