Explanation

Box 1: Enable the Wildlife entity and the annotation entity for mobile offline Note: As part of the 2020 Wave 2 release, we made generally available offline capabilities for model driven apps for users of Power Apps. Makers and administrators can now configure apps to be available offline on a user's device, and users can continue to complete their tasks against the local cache on their phone even with intermittent or no network connectivity. When the network is re-established, the users' changes are seamlessly synchronized back to the cloud.
Box 2: Enable attachments on the Wildlife Details entity and enable Wildlife Details entity for mobile offline.
Box 3: Create a business process.
Business process flows. Ensure that people enter data consistently and follow the same steps every time they work in an app by creating a business process flow.
Note: Power Automate includes several types of processes, each designed for a different purpose:
* Automated flows. Create a flow that performs one or more tasks automatically after it's triggered by an event.
* Button flows.
* Scheduled flows. Create a flow that performs one or more tasks on a schedule such as once a day, on a specific date, or after a certain time.
* Business process flows. Ensure that people enter data consistently and follow the same steps every time they work in an app by creating a business process flow.
* Workflows and actions. Dynamics 365 customizers may be familiar with the classic Microsoft
* Dataverse processes, which are workflows and actions.
