Query on Slice monies reward rate

Hi,

Slice card gives 1% to 2% reward based on spends as monies. Wondering if I spend exactly ₹5L on Slice, it means reward rate for ₹5L monies will be 2% => ₹10k cashback? Or is it tier based where spends below 3L will give 1%, above 5L give 2% etc?

Anyone have any idea about this?

Thanks
