A sticker

A store sticker sent from the composer's sticker tray: the conversation's openStickerTray() opens the tray (DirectStickerTabTrayScreen), its openStickerTab() the sticker grid (DirectStickerPickerGridScreen), and the sticker's own row in the grid's list (stickers) sends itself with send(), an IGDirectStoreStickerSendMutation.

The tray's sticker tab with the store's packs: openStickerTab() lists the first-party batch's stickers as stickers, every pack's in the answer's order.

The tray's emoji tab, the other tab beside the stickers.

A store sticker shown in the conversation after the sticker row's send().
