Wait for an element to appear (up to timeout seconds). Returns 'Found' or 'Not Found'.
AI agents call wait_for_element to retrieve information from Android MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only observes the UI by waiting for an element to become visible and returns a status string. It does not modify, execute, or delete anything. It is a passive read/query operation on device UI state.
From the tool's definition 'Wait for an element to appear... Returns Found or Not Found' — purely polls/queries the UI state with no side effects
