How to send an alert when there have been no leads for 2 days

How to send an alert when there have been no leads for 2 days

Hello,
I want to be alerted when there have been no new leads created for, say, 2 days. It seems like it should be a simple thing to achieve but I'm struggling. I tried asking Zia and this was the answer, but it doesn't fit what I'm seeing on the workflow screen. I have highlighted the instructions that I can't follow because those options aren't there: 

To set up an alert for having no new leads in your CRM for more than two days, you can create a workflow rule with a scheduled action. Here's how to do it:

1. Navigate to Settings > Setup > Automation > Workflow Rules.

2. Click Create Rule.

3. Select the desired module (e.g., Leads).

4. Enter a Rule Name and click Next.

 5. Choose Record type and trigger. For this scenario, select "Created" as the record type and "2 days" as the time interval for the trigger.

6. Add a condition to check if there are no new leads created within the last 2 days. You can use a formula condition for this, such as: `ISBLANK(FIELD(Leads, "LastModifiedDate", "2 days ago")) AND ISBLANK(FIELD(Leads, "LastModifiedDate", "yesterday"))`

7. Add a scheduled action to execute the alert when the condition is met. This could be an email notification, a task, or any other desired action.

8. Save the workflow rule. Now, whenever there are no new leads created in your CRM for more than 2 days, the scheduled action in the workflow rule will be triggered, alerting you accordingly.

Can anyone help me please? Maybe there is a different/better way to do this entirely?

I wondered about creating a custom view to show leads which are less than 2 days old...could that be used to send an email when the view is emtpy?

Thanks in advance,
Emma
