Variations not showing after listing

I have listed my first product with variations. I can see the parent-child variation in Manage Inventory. However, I don’t see the variation option (e.g Style: 1m, 2m, Color: Red, Green, Blue) on the (Parent) listing page. Did I do something wrong or I need to send my inventories in first to see parent-child listing.

I have seen a similar post here.

Not sure it is still valid now.
