Step-by-step explanation:
The Salesforce mobile app allows a range of actions that can be defined to enhance functionality and user experience. These actions include standard actions like Create, Edit, and Delete, as well as custom actions that can be tailored to specific business processes. Custom actions can be linked to Apex code or Visualforce pages to perform complex tasks. Additionally, quick actions can be created to allow users to do things like log calls, send emails, and create records quickly. Global actions enable users to create records independent of any particular object, making it simple to add new data from anywhere in the app. The Salesforce mobile app also supports lightning component actions, which are custom-built Lightning components that can be invoked from the mobile interface. It's important for the actions to be mobile-friendly and designed with consideration for the touchscreen interface.
