I need help with

Hi, I need help with woocommerce shipping classes. I cannot find how to set Freeshipping if the client spends more than 35€ at once. I wish to have a flat rate of 3€, but if the client buys a total amount of more than 35€ I need to set it for free shipping and can't seem to find out how to do this. It is breaking my brains! :slight_smile:
Can you help me? What do you need from me* Thanks!
And you can just call me Maga
