+Alternatively, you can assign a function to `ALERT_MINIMUM_INTERVAL` and/or `REPORT_MINIMUM_INTERVAL`. This is useful to dynamically retrieve a value as needed:
+
+``` python
+def alert_dynamic_minimal_interval(**kwargs) -> int:
+    """
+    Define logic here to retrieve the value dynamically
+    """
+
+ALERT_MINIMUM_INTERVAL = alert_dynamic_minimal_interval
