During the setup of an error alert, which option is NOT required to be configured?

In the context of setting up an error alert, the title for the alert is not a required configuration. When creating an error alert, the primary elements that need to be established include the alert style, which determines how the alert will be presented to the user, and the error message itself, which provides specific information about what has gone wrong. Additionally, an input message can be configured to offer guidance on what kind of data is acceptable in the input field.

However, the title for the alert, while it can be helpful for user clarity and context, is not mandatory. Therefore, omitting a title does not impact the functionality of the alert itself, making it the correct answer in this scenario.
