## How to Implement

Use **openLink()** to start the app with the specified App Linking.

Use **startAbilityByType()** to start applications of a specified type and configure the parameters of the applications to be started. The system prompts the user to select an application to continue the operation. After the user selects an application, the operation continues in the application.

**NOTE**:
1. You need to modify the App Linking in line 67 of `src/main/ets/viewmodel/MessageViewModel.ets`.
2. To start a self-developed app, you need to configure App Linking in the dependence/AppLinkingTestDemo app. It covers applying for a link, certificate, and profile signature.
