thanks for this change @chungwwei

looking at https://m3.material.io/components/bottom-sheets/overview i don't think we want to keep the x button at the top left corner of the bottom sheet - it appears superfuluous. can you please removew? thanks!

also - can you screenrecord a short video to show this works?
