Tap Skip Import. You will import your wallet descriptor once you complete the full setup of your Casa vault

On Passport Prime, tap the light bar at the bottom of the screen to return to the main screen, then tap the QR code icon in the bottom right menu.
In the Casa app, select Deposit funds, then tap the three dots in the top right corner to bring up your wallet descriptor. Scan it with Passport Prime.
Once both scans complete, the Passport Prime signing key is added to your Casa account.
