Duolingo Allow Notifications Sheet

Upon tapping a lesson node, a bottom sheet slides up from the bottom of the screen to prompt the user for notification permissions. Simultaneously, a dark semi-transparent scrim fades in to dim the background. Inside the bottom sheet, the Duolingo mascot (Duo) animates, playfully ringing a yellow bell to draw attention to the prompt. The bottom sheet uses a smooth ease-out transition, while the mascot's animation adds a delightful, character-driven touch to a standard permission request.
