Allow users to enter data to specific records in table(s)

Current situation is as follows: user signs up through a (Airtable) form on our website and enters a table and gets a record ID. In the onboarding process that follows we would like to allow our users to change/add data to their specific records in our tables.

Can anyone please help us figuring out how we can automate this process? Currently we have to manually add the asked information in the right table.

Thank you!

Welcome to the Airtable community. It sounds like you want a portal, such as Stacker or MiniExtensions.
