Product not found: check on other projects (OBF, OPF, OPPFF…) if it exists

[g123k]

Hi everyone,

When there is no product available, we now show this card:

As part of the redesign, we would like to check on other projects if it exists.

The idea on the "product not found" card:

1. Still show a button to create a new product
2. Check in parallel if the barcode exists on OBF, OPF, OPPFF…

If the product doesn't exist on other projects: explain that it's OK to create it on OFF
If the product exists on another project:

• Give a link to open this product (in a Chrome custom tab)
• Allow to still create the product on OFF, but with a different wording ("Are you sure you want to create this product?")

Here are some non-final and ugly mockups:
