To edit an app in your kit, start by click the menu with three vertical dots in the upper-right corner of your kit. Then click Edit App in the menu.
All app icons in the kit will now show a pencil icon in the corner. Click the icon of the app you wish to edit.
On the setup page, you can edit the Kits Display Name and the view permissions for the app. After making your edits, click the Save & Add to Kit button.
Your kit should now show any display name edits to the app on your kit.
Changes in permissions can be checked by using the View As Student option under the vertical three dot menu (will not verify permission changes from Instructors + Assistants to Just me).
