Same discount code with various offers i.e. 30%, 40%, 50%

[Kit_]

Hi Developer,

Recently I am working on the discount code which can offer various offers based on the product tags i.e.

Let's say discount code is 'VIPDISCOUNT' and in the checkout page it should offer the discount offer based on the product tags for example:
if the product tags contains 30% then give 30% off, if product tag contains 40% then it should give 40% off.

Below is the code sample in the script editor, As you can see it gives 10% off based on the 'discount_amount: 10'; is there any way i can mutate(pass the value) the discount_amount value based on the product tags i.e. if line_item.variant.product.tags.include? '30%' discount_amout: 30 elsif line_item.variant.product.tags.include? '40%' discount_amount: 40

PRODUCT_DISCOUNTS_BY_DISCOUNT_CODE = [
  {
    discount_code_match_type: :exact,
    discount_codes: ["TESTCODE1", "VIPDISCOUNT"],
    product_selector_match_type: :include,
    product_selector_type: :tag,
    product_selectors: ["VIPSALE"],
    discount_type: :percent,
    discount_amount: 10,
    discount_message: '10% off tagged products!'
  }
]
