How to use page up/down and home/end keys on iOS?

I am using a physical keyboard with iOS on iPhone (It is a logitech K780).

How do you make the page up/down key work? They seem to work in Safari and Edge. However, they do not work in Pages in Editing mode. They also don’t seem to work in Notes.

Same with the home/end keys. They don’t seem to work at all.

You can use CTL+A or CTL+E in place of home/end.

Are there any shortcut to use in place of Page Up/Down? I’ve seen web articles saying to use FN + arrow keys or Opt + Arrow keys but it doesn’t seem to replicate Page Up/Down.
