[2024] How can the Trickery Cleric's duplicate move?

As part of Invoke Duplicity, the description of the Move Bonus Action states:

Move. As a Bonus Action, you can move the illusion up to 30 feet to an unoccupied space you can see that is within 120 feet of yourself.

But how the illusion moves during these 30 feet isn't defined.
Do I get 30 feet of movement for my duplicate that I can use as I see fit during my turn?
Does the duplicate simply teleport to a single location that I can choose once (or does it move there)?
Can I move the duplicate 15 feet, perform and action, then move the duplicate again for 15 feet?

It's a bit unclear.

Thank you.

Some of these questions are clearly answered just by other rules that exist separately.

Sorry I'm trying to look things up to the best of my abilities but I don't have enough experience to know all of them. Or even most of them, for that matter.

I'd say the illusion moves rather than teleports, based on the wording of some spells, for example:

Moonbeam says "move the Cylinder":

... you can take a Magic action on later turns to move the Cylinder up to 60 feet.

For comparison, Cloud of Daggers says "teleport the Cube":

... On your later turns, you can take a Magic action to teleport the Cube up to 30 feet.
