iPhone Update iMessage Stickers?

[BeK]

Does anyone have any idea how to update the stickers for iMessages? I clearly have a number of stickers that require updating, but when I enter the sticker store there is no option in site to do so.

I forgot that stickers even existed!

They update via the regular App Store for me, just like any other app…
