Can export assets from UI link

Unfortunately, you cannot directly export assets from an Adobe XD "view-only" link. When an Adobe XD file is shared with "view-only" permissions, the recipient is intended to review the design, provide feedback, and inspect properties. They are not granted the rights to download or extract the original design assets. This is to protect the designer's work and control over the source files.

You can contact the person who shared the view-only link and request that they export the specific assets you need for mobile app development and share those exported files with you. Explain to them which assets are required (e.g., specific icons, images, etc.) to streamline the process.
