-You can share direct links to saved Discover sessions, dashboards, and visualizations. When clicking **Share**, look for the **Links** tab to get the shareable link and copy it. 
+You can share direct links to saved Discover sessions, dashboards, and visualizations. Look for the **Share** icon in the toolbar.
+
+When applicable, you can choose to share the object using a relative or an absolute time range:
+
+* **Relative time range**: The link shows current data. For example, if you share a "Last 7 days" view, users will see the most recent 7 days when they open the link.
+* **Absolute time range** (default): The link shows a fixed time period. For example, if you share a "Last 7 days" view on January 7, 2025, the link will always show that exact week of January 1-7, 2025, regardless of when users open the link.
 
 TIP: When sharing an object with unsaved changes, you get a temporary link that might break in the future, for example in case of upgrade. Save the object to get a permanent link instead.
 
 To access the object shared with the link, users need to authenticate.
 
 Anonymous users can also access the link if you have configured <<anonymous-authentication,Anonymous authentication>> and your anonymous service account has privileges to access what you want to share.
