Expand std::vector into parameter pack

I have methods with the following signature:

void DoStuff(int i);
void DoStuff(int i, k);
void DoStuff(int i, int k, int l);

I have a method from where I would like to call the DoStuff methods as follows:

void CallDoStuff(const std::vector<int>& vElements) {
  // What magic is supposed to happen here to make vElements an expandable pack?
  DoStuff(vElemets...);
}

Is there any chance to achieve this? Is using std::index_sequence the right way? If yes, could you please provide me a simple example how to apply this to my problem?
