Open All in the QR Codes section. Filters lets you search by Keyword, which covers name or slug, Number of Scans, Creation Date, and optionally Type. Apply Filters to narrow the list; use Clear Filters to remove them.

Page Settings controls the number of items displayed per page and whether QR previews are shown. The editor states that previews are available only when the visible count is no more than 25 on desktop or 5 on mobile.

If you cannot find an item, clear filters, check the page count, and look in Recently Deleted. Use a descriptive saved name to make future searches easier.
