Mac keybindings not working in OneNote

I've remapped my home and end keys to behave like Windows using https://damieng.com/blog/2015/04/24/make-home-end-keys-behave-like-windows-on-mac-os-x/ Shift+end highlights text from the cursor to the end of the line. Shift+home highlights to the beginning of the line. This works in all applications I've used since remapping - EXEPT MS OneNote. Anyone know why OneNote might behave differently? MS Outlook, MS Word, Mac Text Edit, Mac Notes - all work as I'd like. What would cause OneNote to respond with an error beep as compared to the other apps? I don't have any custom key mappings in system/keyboard setup for OneNote. MacOS: 12.3.1 MacBook Pro M1, 14"
