[Prestashop] Managing referrals as vouchers rather than points

Hi, I would like to manage the referral plan in a different way.
Let me explain: I would like that every time you invite a friend and he buys, he gets a 10€ voucher, for example, and when you reach 100€ it is generated. The management of the other points (e.g. every time he buys a product he accumulates points) should continue as it is today.

OK, but maybe I forgot to tell you something.
If I bring a friend, to be entitled to points, he must buy at least 50 euros, how do I configure the system?
Another thing, I have to continue to have the possibility to get more points for example by buying products or leaving reviews that accumulate, but they must be "independent" from bringing a friend.
I hope I have explained myself well

If you are setting a rule with minimum order total type to all orders in all, you cannot set the minimum for each order for it to be taken into account.

I'm sorry but I'm not sure I understand, what I'm supposed to do I can't do?
Any advice?

this rule:
+ each order minimum has to be 50 euros
is valid every time I refer a friend and therefore I only have to get points if my friend buys a minimum of 50 euros.

no it should work like this.
I am a registered customer on the site and I recommend you through your plugin, if you register on the site and buy at least 50 € you will earn for example 10 points and I will earn another 10 points, if I recommend other 9 users who buy at least 50 € will have another 90 points, when I get to 100 points earned exclusively by the recommendation of other customers I will have a discount of x euros.
In the meantime I can earn more points such as buying products or making reviews or other but these points will have to go "in another account" that will allow me to be entitled to other discounts.
I hope I have explained myself
Thanks a lot
