Action Center: How To Delete Tasks In 20.10

How to delete Tasks in 20.10 Action Center?

The ability to delete tasks in Action Center was not added until 21.4.

In order to delete a task in versions prior to 21.4, a query needs to be run directly on the DataBase. The tasks are stored in the dbo.tasks table and an item can be marked deleted by setting the 'isDeleted' field to True.

One way to do this would be to assign all the Tasks to a known user ID and then to mark them deleted.

The query would look something like:
Update dbo.Tasks
Set IsDeleted = 1
Where AssignedToUserId = <Known User ID>
