How to add virtual wall ROS2

Hei everyone, i have problem when tried add virtual map ROS2

I watched this video in ROS1 and want to deloy in ROS2:
So, I don’t know if there is a package that performs this function. Or if not, what do I need to do to get it in ROS2

Hello @duygiangtemp , you can create these virtual walls by using the Keepout Zone mask, which is exactly what you are showing in this image.

Thank you, I followed what was done in the Advanced Nav2 course. But is there any way to edit the realtime costmap as shown below with ROS2? I’m thinking about writing a package but don’t know where to start. Can you suggest me some ideals or packages?
