Hi averyone,
   I have created an aura component that accept sobjectAPI Name and its Fields. This aura component show of Record detials using given values . I want to use this component in App builder . I have use <design:attribute name="mycustomlist" datasource="apex://MyCustomPickList" /> to get Input for sObject API Name but I ca'nt find any way to get multiple fields . salesforce also use multiselect look like given Image. so  please provide any way to use multi select in app builder.

Easy challenge, copying the code of CloudNewsTrigger and including small changes, but I have stucked with the UserId.

Using this code for OrderEventTrigger you will pass the course:
 

trigger OrderEventTrigger on Order_Event__e (after insert) {    
    // List to hold all tasks to be created.
    List<Task> tasks = new List<Task>();
    
    // Get queue Id for task owner
    //Group queue = [SELECT Id FROM Group WHERE Name='Regional Dispatch' LIMIT 1];
     String usr = UserInfo.getUserId();  
    // Iterate through each notification.
    for (Order_Event__e event : Trigger.New) {
        if (event.Has_Shipped__c == true) {
            // Create Task to dispatch new team.
            Task ts = new Task();
            ts.Priority = 'Medium';
            ts.Status = 'New';
            ts.Subject = 'Follow up on shipped order ' + event.Order_Number__c;
            ts.OwnerId = usr;//queue.Id;
            tasks.add(ts);
        }
   }
    
    // Insert all tasks corresponding to events received.
    insert tasks;

}

Good luck!
