To replace Count tool icon by custom icon [Pdfjs-express 7.0]

Please let me know how to change this count tool checkmark icon color.
I don’t know how to change color of the icon. But for other annotations, I am using this -

const tool = this.viewerInstance.docViewer.getTool(annotation);
tool.setStyles(() => ({
Scale: [[1, ‘m’], [10, ‘m’]],
Precision: 0.01,
StrokeThickness: 2,
StrokeColor: new this.viewerInstance.Annotations.Color(92, 142, 184),
}));
this.viewerInstance.docViewer.setToolMode(tool);
