Provide helpful information in the message body

Keep the modal's body text for secondary details, like explaining why an action is needed or adding extra context. This text shouldn't echo the title but support it. Be aware that users often skim through the body text, as it sits lower in the visual hierarchy. If there's vital information that users absolutely need to grasp the modal's purpose, include it in the title.

Essentially, your title should capture attention and convey urgency, while the body text offers supplementary insights, without relying on users to read it thoroughly.
