Trigger "While scrolling in view" animation with anchor link

I have an animation to reveal the footer behind another section while you scroll.
On the navigation I have a link that is an anchor to the footer, but when clicking it doesn’t reveal the footer, I have to scroll to trigger the animation.

Is there a way to fix this and trigger the animation with the anchor link?
