Which is the right or left control sticks on the controller?

But it doesn't have a function on the guide menu or dashboard right even if you jiggle it up and down or side to side or circles it doing that doesn't lead to secret functions or menus? I just want to make sure it doesn't

And it does have a function on spotify though it navigates like the left stick too

the Left stick is the one by the D-Pad, and is usually used to control character movement within a game.

the Right stick is the one by the buttons and is usually used to control the camera/view/aim within games

hope this helps

the right stick sometimes has a function in some apps. for example; the left stick might scroll the screen/page and the right stick might move the cursor around the screen/page, or the left stick is used to select items on the screen and the right stick
scrolls the selected text

the Left stick is the one by the D-Pad, and is usually used to control character movement within a game.

the Right stick is the one by the buttons and is usually used to control the camera/view/aim within games

hope this helps

And the right stick doesn't have any function effect on the guide menu or dashboard when you jiggle it up and down or side to side or in circles on the guide menu or dashboard like for example it doesn't have a secret function or menu when you jiggle it up
and down or side to side or circles during the guide menu or dashboard?

You use it in all games to look up and down and around in FPS, TPS and lots of other games. Lara Croft, Halo, Gears, Doom, etc...
