Tab component and interactions

Apologies for asking help with a recurring issue!

The section ‘Five Stages off Content Operations’

When the page loads I want it to show Emerging as the initial state and the arrow above it to slide in from the left. When you click on another tab, the Emerging tab fades out to 30% and the arrow disappears to 0%. (Each tab will have it’s own arrow)

I can’t figure out whether it’s more effective to have it part of link tab or putting each of the arrows in their five sections - either way I’m struggling!

Appreciate any help in advance!
