Invisible token swapper?

[MartianXi]

Typically playing 5e but this may work across other rulesets...

Just curious if anyone has any unique tricks for when a player character goes invisible. Like a token swapper extension maybe?

I think I've heard of an extension that can swap tokens. But no, in 5E when something is invisible we just put the invisible effect on them. Just because a token is invisible, doesn't mean the players don't know where it is.
