Customization options for in-app announcement popups

Description: As a user, I would like better customization options for In-App Announcements to ensure the layout and design align with my expectations. Problem: Currently, images within the announcements appear cropped and do not display in full width, as they do in the example provided in the help center article. Additionally, the announcement area appears small and not centered. The Call to Action (CTA) button design is limited, and Markdown is not properly supported in the widget announcement. Benefit: Improving customization options, such as allowing images to display fully without cropping, enabling centered layouts, resizing popups, and customizable CTA buttons, will help make announcements more visually appealing and professional. It will also allow users to maintain consistent branding and improve user engagement.
