Watch only Bitcoin addresses on Sparrow

This task may seem easy, but it is very difficult to complete. I want to see my Bitcoin address on Sparrow. This is a multi-signature address that starts with 3*. Here’s what I’ve tried so far:

new wallet

Policy Type: single signature

Script type: Nested Segwit or Legacy (neither will work)

Master Fingerprint: 00000000

induction: Meter/49’/0’/0′

xpub: Bitcoin address starting with 3.. (e.g. 33WVxauW21vZEXn2r7gxAbENLRnwtVeWou)

The “Apply” button is not active. Something seems wrong.
