Cloud Storage File Sharing App Permission Modal

Design cloud storage file sharing app permission modal with practical UI structure, strong UX signals, and simple productivity visual language. Show a permission modal with people search, role dropdowns, link settings, expiration date, security warning, and share button. Include people search, role dropdowns, link settings, expiration date, and security warning while keeping the product useful for business users. Make the hierarchy easy to scan, with meaningful labels, realistic microcopy, responsive spacing, hover or tap states, and accessible contrast. Add empty, loading, and error states where they would naturally appear, so the interface feels like a complete UI/UX case rather than a single decorative screen.
