Navigate to other component with formattedURL

Question

In my component I have this formattedURL :

<lightning:formattedUrl 
        value="{!notification.objectUrl}"
        label="{!notification.objectName}"
        target="_self" />

I make my notification in my Helper where I use a JSON that I get from a POST call. When I receive the JSON I have a phone number and from it I find the object that possess this number.

So basically I have something like that :

const newNotification = {
        time: $A.localizationService.formatDateTime(
          message.data.payload.CreatedDate,
          "HH:mm"
        ),
        message: messageText,
        user: userId,
        objectType: objectType,
        objectName: objectName,
        ObjectId: objectId,
        objectUrl: "MyURL",
        phone: phone
      };
      const notifications = component.get("v.notifications");
      notifications.push(newNotification);
      component.set("v.notifications", notifications);

When the Phone number is unknow from salesforce I modify it this way :

const newNotification = {
              time: $A.localizationService.formatDateTime(
                message.data.payload.CreatedDate,
                "HH:mm"
              ),
              message: "New Call !",
              user: "",
              objectType: "",
              objectName: "Unknow",
              ObjectId: "",
              objectUrl: "",
              phone: res.Phone
            };
            // Save notification in history
            const notifications = component.get("v.notifications");
            notifications.push(newNotification);
            component.set("v.notifications", notifications);

So in my formattedURL I use objectName (here Unknow) and the objectURL to get a link to the object through a call history. Now when the phone number is unknow I want put a link to an another component that will allow the user to search in salesforce. I already used $A.get("e.force:navigateToComponent"); that I use to open my component automatically. But I want to give a way to open it later through history. How can I get the url value of an another component ?
