Add a custom bubble before the task

Hello.,

Is there anyway to add a custom bubble like a circle with "1" before the task?

I want to display if the task has notifications and for that I am trying to use the customTaskTemplate

Please check this example of using taskTemplate for a custom bubble: https://stackblitz.com/edit/vitejs-vite-zp8qd9sc?file=src%2FMyComponent.jsx,src%2FGanttComponent.jsx&terminal=dev
But unfortunately now we have a bug in a react gantt component related to task update.
