Default Do "starshades" make sense?

It's mentioned in this speculative space telescope video. The idea is to create an eclipse using a large, calculated shade which would allow a star to be occluded and planets around it to be seen. I get occluding the star, but how would a much, much dimmer planet be seen at all, even by a large telescope?

Enough light is reflected from a great many planets to be detected
with a telescope this size. As long as the central star can be
occluded.
