Question Find a known string in an object in a project

There's a quite specifically unique string I've used in a project, that I can easily remember and know is in a TextMeshPro object within that project, and I'd like to find the object that it's in, or the prefab it's in, but am unable to open the project on the original machine with its original project layout because of this:

Is there a way to search through the assets to find the object/prefab with this string in the TextMeshPro object?

Finder is not helping, it seemingly can't see into prefabs.

Opening the project on another computer, because of this nightmare: https://forum.unity.com/threads/load-default-layout-looping-error-cant-open-editor.1397914/

Hasn't revealed a way to find the object... and I don't really want to spend a couple of days going through every text object and prefab to find it.
