How does anyone obtain use of this function or any console functions inside a script? I keep getting errors when compiling

Console functions aren't available via the scripting language unless is has a direct replacement documented in the Wiki. You'll have to wait for SKSE to possibly add the link in the future.

Actually with a little cool tricks i was able to use this feature via Quest Conditions with a global script, if First Person was true it would do some stuff, then reset the quest state, if false it did other things this way it kept checking for First person view
