Invert horizontal scrolling with mouse wheel on ScrollRect

Hi there.

With vertical scrolling, when I scroll down with mouse wheel, content scrolls down as expected.

I am trying to use ScrollRect with content positioning horizontally(vertical scrolling is disabled).

When scrolling down with mouse wheel, I expect to see content on the right, but instead it scrolls towards the left.

How do I inverse horizontal mouse scrolling?

On the Scroll Rect change the scroll sensitivity to a negative number.
