A due date is required to be set on the task before reminders can be created. If one is not already set, you will be prompted to do so.
In the Add Reminder modal, you can select users to receive the reminder, set a date and time for the reminder to be sent, choose a reminder type, and add a custom message.
When choosing how to set the reminder, you can select a predefined option or set it to be relative to the task's due date.
When using the relative option, you can set a custom number of days and choose whether it should be sent before or after the task's due date.
At the bottom of the modal, you can set a time and reminder type as well as include a custom message.
