WorkApps are customized apps that give you access to only the information and interactions you need to perform specific tasks. You might get an email saying you've got access to a WorkApp, or maybe you tried to access it some other way.
When you try to access an app, you might receive a message saying "You currently don't have access to this app."
Click Request access to send a message to the app owner. When the owner grants you access, you'll be notified by email and the app will appear on the WorkApps homepage (https://workapps.smartsheet.com/) under Apps Shared with you.
