The critical path is the time required to complete the longest chain of dependent activities.
To display the critical path in your dependency path, you must first highlight the end element of your dependency path.
To do this, go to the table view of your Roadmap and add the Highlight column.
Then click on the light bulb at the end of your path, which will turn orange, indicating that the element is highlighted.
Then return to your planning view and check that the "Show critical path" parameter is active in the Gantt parameters.
The critical path is not updated automatically.
To display it, click on the icon of the map where you are located and select the "Updated dependency & critical paths" option.
Your critical path will then appear in the schedule in red.
