How to add "Ground Truth" version of ScreenshotFunctional Test

I can’t seem to find anywhere in the Automation Overview Docs [link][1]. But there’s a method added somewhere in the release notes for 4.17 under “UI” for adding Ground Truth for a ScreenshotFunctional : [RN][2]

How do add a “Ground Truth” screenshot though the Unreal Editor/Frontend ?

You have to go to “Screenshot Comparison” and click “Add New!”. However this button is only enabled if you have source control enabled.

Hi, can you help me? I try get screenshot, but “Screenshot Comparison” always empty.

Did you ever manage to make it work? I’m also stuck with the same problem.
