Offering a discount, free item, or any other reward in exchange for a review breaks their policy, and it doesn't matter whether the incentive is tied to leaving a positive review specifically or just for leaving one at all. Reviews Google identifies as incentivised can be removed, and a pattern of it puts your whole Business Profile at risk.
