How is に used in にできる here?


Slight disclaimer. I did read the following post, [Meaning of に in
～にできる](https://japanese.stackexchange.com/questions/53596/meaning-
of-%E3%81%AB-in-%EF%BD%9E%E3%81%AB%E3%81%A7%E3%81%8D%E3%82%8B/53597) , but did
not see it's reasoning directly translating to my sentence.

Here is sentence in question:

> 「五つ子だからミクにできることは他の四人にもできる。」

So the speaker is saying that since these girls are quintuplets, if one of
them can do something, then the rest of them should be able to do it too. I've
seen that にする can mean "to decide on something" or "to make" and できる is the
potential form of する, but I can't see how that would work here. What is it
that the girls can do/make? How does に as a the location particle work here?

Any help would be much appreciated. I feel that there is something that has
gone unsaid here and I can't put my finger on it.

**EDIT.** Or is all what comes in front of こと just a descriptive clause and
what she can do/make is the abstract こと?




Because they are quintuplets, anything Miku can do, the other four can also
do. The に should be used in a similar sense to にする, and こと is exactly as you
say.
