Option 1: Add another email type column, make it a row owner, and add your Admins email address in every row.
Option 2: Use roles as row owners.
– Add a Role column to your Users table, and set it as the role column in your User Profiles configuration
– Give your Admin user a role (eg. Admin)
– In every table where you have row owners, add another Text type column and make it a row owner, then add your Admin users role name in every column
Option 2 is more scalable and easier to manage, especially if you have multiple admin users, or your admin user can change. Just be aware that any user that is given a role will count as a private user.
