Can we please add the “copy” icon (two overlapping rectangles) to the list of supported icons?
Use case: any time you want to add a button for copying something (like a discount code) to clipboard on the checkout/order status pages. Thanks!
Hi, @aaron_barbieri
Hope you are doing well.
This is a great suggestion and a very common use case. 
Right now, checkout and order status pages are built using Shopify’s UI extension system, and those surfaces are intentionally restricted.
Only the icons that are included in Shopify’s supported icon component set can be used, and custom icons or arbitrary SVGs aren’t allowed in checkout or order status extensions.
Unfortunately, the “copy“ icon (the two overlapping rectangles) isn’t part of the supported icon list at the moment.
Because these pages are security and conversion-critical, Shopify keeps the UI very controlled and consistent, which is why even widely used actions like “copy to clipboard” usually rely on text-only buttons (for example, “Copy code“) rather than icons.
This is also the pattern shown in Shopify’s own examples.
That said, the use case absolutely makes sense, and this kind of feedback is valuable.
If enough merchants and partners request it, Shopify does occasionally expand the icon set.
The best way to push this forward is to submit feedback through Partner feedback channels or GitHub discussions for UI extensions.
In the meantime, the recommended approach is a clear text button with a confirmation message like “Copied!“ to keep things intuitive and compliant.
Hope this helps to you!
