How to find-replace in a selection in Powerpoint?

We recently updated to Powerpoint 365 (Version 2512 Build 16.0.19530.20184), where they replaced the Ctrl+H find-replace popup window with a fancy new sidebar. While before, this popup would look in your selection, the new sidebar starts from the start of the slide deck (even looking in the slide master before looking in the presentation). Hence it is now impossible to change all $ to € only in the selected slides.

What am I missing?
