Hi @Dhir-9db3! - Thanks for your feature request!
To make sure I understand the request correctly, I assume you're looking for a way to let your app users edit/update existing data. If so, perhaps this is what you're looking for:
In the App Wizard, when setting up the detail screen, you can click on the pencil next to the columns you're displaying to make it "editable". Once the column is "editable", your app users can change the data in real-time.
Here's a reference in case it's helpful. Please see step 7.
Hope this helps! But please do let us know if you have any other questions/feedback. Thanks!
