How to "Undo dismissed creations in Google Photos"?

This answer here solved my problem!

Undo dismissed creations in Google Photos

When accessing from web version, in the bottom part of the assistant page, there is a link to discarded creations. You have to scroll down the page.

You have to be very patient to scroll all the way down because Google Photos always show your other albums first before the link mentioned.

I just captured the link URL, in case you still cannot spot it.
