We need to change the French term of "Recherche de matricule" in the worksheet plan

Summary:

We have a requirement wherein the "Recherche de matricule" in French meaning "Person Number Search" in WFC plan worksheet should be change.

When I checked inside the Sandbox > User Interface Text and search for "Recherche de matricule", I didn't find the exact term or no results was shown.

Is there any other way to update the text in dropdown list?
