Airtable’s interface doesn’t offer the ability to limit records, but you can limit records with the Records List app:

Thank you for support but I’m asking on the topic of automation, not an app for manual use. I mean how can get the required number of records automatically

You can’t unless you write your own custom Javascripts to do this.

If you don’t want to write Javascripts, you can also use a external automation platform like Make.com to do this as well.
