You will need to select your restore point as well. In this case, I decided to restore back to midnight UTC on a particular date. Note that the dates are UTC rather than your local timezone!
After selecting your restore point, you pick the target server and can decide a couple of things. First, you can put this database into an elastic database pool, which makes cross-database connections a lot easier. Second, you can choose a different pricing tier. Because I only needed this database for a few minutes, keeping it at P2 Premium was fine; the total restore time meant that we spent less than a dollar bringing the data back to its pristine condition.
Be aware of the time for restoration; it can be very slow.
