is getPerformanceData() working?

Description

Hi, actually i can´t find getPerformanceData method from driver. I'm triying all classes and interfaces to instantiate and get that method, there isn't.

Did you remove that method?

GetPerformanceData

Environment

• Java client build version or git revision if you use some snapshot: 7.5
• Appium server version or git revision if you use some snapshot: 1.20.2
• Desktop OS/version used to run Appium if necessary: Android
• Node.js version (unless using Appium.app|exe) or Appium CLI or Appium.app|exe: Appium.exe
• Mobile platform/version under test: Android 7.0
• Real device or emulator/simulator: Real Device

Start by inspecting AndroidDriver's public API for getPerformanceData and compare it with the linked Appium command documentation; use the Java test class and Maven dependency shown to reproduce against client 7.5. Done means confirming whether the command is exposed for this driver and version, then recording the supported usage or incompatibility.
