Why do it:
To view or hide the statistical details (such as recipients, preview, and delivery/open rates) of a specific WhatsApp message.
Procedure:
1. Access the page containing the WhatsApp marketing message statistics.
2. Locate the section related to the message whose details you want to view, identified by the title (for example, the message name, as defined in <?= $whatsapp_detail['name']; ?>) and the WhatsApp icon (<i class="ibox-icon fa fa-whatsapp fa-3x"></i>).
3. Look for the section's tool panel, identified as ibox-tools, in the upper right corner of the box.
4. To expand the section (if it is currently closed), click on the expand/collapse link, identified by the arrow icon (<i class="fa fa-chevron-up"></i>).
5. Once expanded, the section will display statistical data (stats-container) and the Recipients and Preview tabs.
6. To collapse the section again (hiding the details), click once more on the same expand/collapse link (the icon will change direction, typically showing a downward arrow).
