You have the correct software.

Try this:-

Select the right eye.

In the properties panel ensure that "bending" is turned on. Some are off by default which may cause issues but we'll deal with those later.

Go to the Poser menu: Object > Create magnet.

Select the new magnet and in its properties panel click "Add Elements to deform". Add the head.

Still with the magnet selected go to its parameters panel and increase the scale.

Repeat for left eye.

You may need to increase the scale of the Magnet Zone to include more of the head. Also position the magnet base to be at the center of the eye.
