Subscription SaaS: limit Airtable rows per user

I have an app on Softr which allows users to create automated content via complex automations. I use Airtable as the database.

Is there a way to monetize this so that the users can add only X number of new content pieces (rows in an Airtable table) per month? I know how to do this in Stripe, but how can I create the subscription model and follow it in Softr and Airtable.

Also, UX wise it would be important to show the user how many pieces of content they have left in their respective subscription period.
