How to close a scheduled repeating task.

Here I'm cancelling all tasks but I want to cancel a single task. How to do it

Here I'm just cancelling all tasks by $this->plugin->getScheduler()->cancelAllTasks();

 

instead of cancelling all the tasks, its advised to cancel the task via its handler

 

How give me an example plz

 

When canceling a task in pm4, please throw CancelTaskException.

Considering using this:
use pocketmine\scheduler\CancelTaskException;
throw new CancelTaskException();
