How to copy class instance (implemented as pImpl) from local variable on stack to memory and set pointer to it

I am not sure how to do this properly: I have class with a member variable which is pointer to MyOtherClass

class MyClass {
  ...
  MyOtherClass* myOtherClassPtr;
  ...
}

And I have a factory function which returns instance of MyOtherClass by value. I want to copy that value so that the myOtherClassPtr points to it. Is the following code a proper way or there is a better way?

auto myOtherClassInstance = Factory::CreateInstance();
myOtherClassPtr = new MyOtherClass();

// this line should use copy assignment operator, is that correct?
*myOtherClassPtr = myOtherClassInstance;

Just fyi, MyOtherClass is implemented using pImpl and has all special members - header:

class MyOtherClass final {
public:

    explicit MyOtherClass();
    ~ MyOtherClass();
    
    // movable
    MyOtherClass(MyOtherClass&& options) noexcept;
    MyOtherClass& MyOtherClass =(MyOtherClass&& options) noexcept;
    
    // copyable
    MyOtherClass(const MyOtherClass&);
    MyOtherClass& operator=(MyOtherClass& options);
   
    ...

private:
    class Impl;
    std::unique_ptr<Impl> impl_;
}

implementation:

class MyOtherClass::Impl {
  ...
}


MyOtherClass::MyOtherClass() : impl_(std::make_unique<Impl>()) {}
MyOtherClass::~MyOtherClass() = default;

MyOtherClass::MyOtherClass(MyOtherClass &&) noexcept = default;
MyOtherClass& MyOtherClass::operator=(MyOtherClass &&) noexcept = default;

MyOtherClass::MyOtherClass(const MyOtherClass& options)
    : impl_(std::make_unique<Impl>(*options.impl_)) {}
MyOtherClass& MyOtherClass::operator=(MyOtherClass& options) {
    swap(impl_, options.impl_);
    return *this;
}

Also, MyClass is objective c class with myOtherClassPtr being atomic @property, but I thought it is not important for this question.
