 Some types of rules enable you to further refine the conditions under which actions run.
 For example, you can specify that actions run only when an alert occurs within a specific time frame or when it matches a KQL query.

-Each connector supports a specific set of actions for each action group and enables different action properties.
+Connectors have unique behavior for each action group.
 For example, you can have actions that create an {opsgenie} alert when rule conditions are met and recovery actions that close the {opsgenie} alert. For more information about connectors, refer to <<action-types>>.
