Refreshed UI Design Updated the download button graphic with a cleaner, refreshed look.

2.7 - Resolved a bug where the download button on IG Stories was unclickable due to Instagram's transparent navigation overlay.Repositioned the download button to the bottom right corner to prevent interference with native mute buttons and the reply bar.
