You can see them with a naked eye so it's not that minuscule. Either just before sunrise or just after sunset, when the sky is black, and so your eye adapts and you start to see things otherwise too dark to be visible on the sky (stars), the Starlink satellites reflect the light from the Sun (because they are higher than you and so their daylight is longer, earlier sunrise, later sunset).

You can see a star with the naked eye even though it coverers no space on the sky. The size is not relevant.
