magento2.3 – Shipping cost calculated on subtotal Magento 2.3

I need to set my shipping amount to be a percentage of the subtotal

My requirement would be: minimum of 7€ and 7% of the subtotal if more.

I can see that in flat rate you can set a fee with a percentage, but it’s calculated o the shipping cost, and not from the order itself.
(ex. it’s giving me 7,49€ with a shipping price of 7€ and a fee of 7%, while the subtotal is 10€)

Can I get the wonted requirement with default settings? If not, which extension should I use?
