   Table 1 Parameters for creating an add-on application

   Parameter	Description
   Add Icon	Click Add Icon to add an icon for the new application.
   Label	Label of the application to be created. The value contains a maximum of 80 characters. A label uniquely identifies an application in the system and cannot be modified after being created.
   Name	Name of the new application. After you enter the label value and click the text box of this parameter, the system automatically generates an application name and adds the Namespace__ before the name. The naming requirements are as follows: The value cannot exceed 31 characters, including the prefix namespace. To prevent duplicate data names among different tenants, each tenant must define a unique namespace when first creating an application. A tenant can create only one namespace. After being created, the namespace cannot be modified. Start with a letter and can contain only letters, digits, and underscores (_). It cannot end with an underscore (_).
   Category	Category to which the new application belongs. Select a value from the drop-down list.
   Description	Enter the description of the application. Value: 1–255 characters.
   Advanced > Runtime Version	Runtime version that the developed asset packages depend on. If this version is inconsistent with the offline version, incompatibility issues may occur.
   Dependency	Application or solution on which the new application depends. The dependent application or solution must be of the asset package type. That is, the dependent application or solution must be an asset package in Assets > Installed on the low-code development page. See Figure 2.

6. Customize the application, for example, by using flows in the dependency application.
   1. In the navigation pane, choose Logic and click + next to Flow.
   2. On the Add Flow page, select Use existing flow, select a flow, and click Add.

      After the flow is added, the page for customizing flows is displayed.

   3. Customize the flow.
   4. Click in the upper part of the page. On the Save As page, set Type to New Version or New Flow and click Save.

      When the add-on application is packaged, only the customized content can be packaged. The dependent content will not be packaged and released with the add-on application. Install the dependent content in the corresponding environment by referring to Releasing and Deploying Applications Developed on Huawei Cloud Astro Zero.
