Can't Toggle to Third Person View (PS5)

[Mastiff Dude]

I cannot toggle from first person, to third person view.  I was having difficulty figuring out which button(s) to press in order to toggle because it isn't mentioned anywhere in the CODEX that I could find.  I finally watched a YouTube video, and apparently you need to press and hold the pad "button".  But that doesn't work either.

1. Is there something I need to change in the SETTINGS menu to activate Third Person?
2. Am I pressing/holding the wrong button?  What is the correct action to take in order to toggle?
