Salesforce does not offer the capability to auto-refresh list views (without clicking the Refresh button on the list view or refreshing the browser), so come to vote for this idea exchange, 20,840 points as of 12 Aug 2022.
The workaround is to add this Chrome extension called Salesforce Grid Refresher, it is a simple extension that does the job, which is the refresh all list views every 1 minute, and yes, you can't adjust it :(
Note: since version 1.5, you can adjust the refresh interval from 5 seconds to 15 minutes. Great job to the developer and thanks for listening.
This tool is particularly useful when you need to monitor a list view, such as new cases created or assigned.
