Hi, I am not sure exactly when to use Pt as the electrode. Can anybody please explain and give an example?

In the solutions manual for the 6th edition 14.13, it states that "Pt is necessary when both oxidized and reduced species are in the same solution" and that it is necessary for "gas/ion electrode reactions"

Pt(s) is an inert electrode, meaning it helps with either reduction or oxidation without actually being changed in the reaction. It must be included in the cell diagram when an solid metal is not present on either the anode or cathode side. It aids in either the reduction or oxidation of aqueous ions.

Is Pt(s) the only other substance you would add in any scenario?

Would you add Pt(s) to both sides?

You would add Pt(s) to whichever side lacks solid metal.

You would add Pt(s) to any side that does not have a solid. This allows electrons to be transferred.

Pt is added to a reaction that does not have a conducting solid, and is added on whichever side needs it, not on both sides.

We use Pt (s) when the reaction lacks a conducting metal, so if we have (aq)|(g)||(aq)(aq) we would add Pt(s) to both sides

I think you can add any inert conductor (I think any solid metal), but Pt(s) is just the most commonly used.
