This huge asterism actually does appear to be a big sq. sample, with 4 medium-bright stars marking the corners. Draw a line by way of the Nice Sq.’s two westernmost (or right-hand) stars, and lengthen that line southward to land on Fomalhaut.
From the Southern Hemisphere:

You’ll nonetheless draw your line southward, however, in your sky – beginning on the Nice Sq. – meaning you’ll draw the road upwards to Fomalhaut. So, simply take the chart under, and switch it upside-down!
Backside line: On November 29 and 30, 2022, use the moon to search out the star Fomalhaut. Then, when the moon is gone, use the Nice Sq. of Pegasus. And when you’ve discovered Fomalhaut, you’re in your strategy to visualizing looking our galaxy’s south window into intergalactic space.
