fuel & induction system cleaning question

Hi all,
I have a 2006 Dodge Caravan. At about 15,500 miles, the dealership
did a fuel injector flush.
They have since gone out of business, so I took my vehicle to a nearby
shop for an oil change, and they recommended a "3-step fuel &
induction system cleaning."

My vehicle is currently at approximately 19,100 miles.

So, before I spend $100, does this "fuel & induction system cleaning"
need to be done? Is it the same thing as the fuel injector flush that
was done previously?

Also, is the fuel injector flush something that needed to be done?

Thanks,
Josh
