UXP for Premiere - How To Marker Change Color

I have another question while migrating marker logic from CEP to UXP.

In CEP, the previous code looked like this:

var newMarker = markers.createMarker(Number(markerInfo.in)); 
newMarker.name = markerTitle;
newMarker.comments = markerComment;
newMarker.end = Number(markerInfo.out);

if (markerInfo.colorType) {
  newMarker.setColorByIndex(Number(markerInfo.colorType));
}

Since createMarker() returned the marker object, I could immediately modify properties like color.

In UXP, however, markers are added using actions.
When I use createAddMarkerAction, I’m not sure if there’s a way to:

1. get the newly created marker object back, or

2. keep a reference to it after creation.

const project = await ppro.Project.getActiveProject();  
let success = false;

project.lockedAccess(() => {
  for (let i = 0; i < markerInfo.length; i++) {
    const markInfo = markerInfo[i];

    const duration =
      markInfo.out && markInfo.in
        ? ppro.TickTime.createWithSeconds(markInfo.out - markInfo.in)
        : ppro.TickTime.TIME_ZERO;

    success = project.executeTransaction((compoundAction: any) => {
      const addMarkerAction = markers.createAddMarkerAction(
        markInfo.title || '',
        markInfo.markerType || ppro.Marker.MARKER_TYPE_COMMENT,
        ppro.TickTime.createWithSeconds(markInfo.in || 0),
        duration,
        markInfo.comments || ""
      );

      compoundAction.addAction(addMarkerAction);

      // After adding a marker, is there a way to retrieve it?
      // const markerList = markers.getMarkers();
      // const changeMarker = markerList[markerList.length - 1];
      // if (changeMarker) {
      //   const changeColorAction =
      //     changeMarker.createSetColorByIndexAction(
      //       markInfo.colorType || ppro.Marker.MARKER_COLOR_NONE
      //     );
      //   compoundAction.addAction(changeColorAction);
      // }
    });
  }
});

Questions:

• After executing createAddMarkerAction, is there any supported way in UXP to obtain the newly created marker object?

• Is it safe to assume the newly added marker is always the last item in markers.getMarkers()?

• If so, do I need to run another lockedAccess() / transaction to change its color afterward?

• Or is there a recommended way to set marker color at the time of creation (similar to CEP) so that a second action is unnecessary?

I’m trying to find the best practice for replicating CEP-style marker creation and modification in UXP.
