How to restrict editing SP Items from SharePoint Online Web UI?

Question

I am making powerapps on SP Online, and I want users to only view and edit items via powerapps, and not from the SP UI. I am following 3 tutorials here

https://blog.josephvelliah.com/restrict-smart-users-data-entry-on-sharepoint-list-associated-with-powerapps-app

I tried to make a copy of contribute and remove the "view application pages" and then set an account to that. However that account could still edit items in the list from the SP UI.

Does anyone know what's wrong?

Per my test, in addition to grant users with custom permission, you should also activate the "Limited-access user permission lockdown mode" feature in the site collection features.
