Gradient Editor?

[jeff43222]

I found this in the Affinity Designer 2 help:

The Fill Tool lets you draw a simple color gradient, solid or bitmap fill across your object. The created fill path can be edited directly on the object to introduce more than two colors along the gradient path, introduce opacity, reposition added colors or control color transitions. You can also apply a more complex gradient via a Gradient Editor.

Sounds nifty. Where might one find this "Gradient Editor?" The help documentation seems to be implying that I should search for some other software that has this tool since I was unable to find any "Gradient Editor" in any of the Affinity apps, and the help documentation doesn't point to one.

Further down in that help article it explains the different ways to modify gradients.
