Only users who take part in the Task can access it
The Tasks are only accessible by the users who take part in them. Only the responsible and following people can access Tasks. Each Task has one responsible person and can have many followers. If you are alone in the Task (set as responsible), only you can access the Task. If the Task contains more followers, they can also access the Task. Unconnected tasks that are not connected to any item cannot be seen by anyone else within the system.
In other words, access to Tasks is based on users in them and not roles they have.
