How to Rotate sprite to touch point in Unity3d?

Question

2D

I have an empty object that I've thrown a hand-like sprite into with an edge so that it can rotate properly. For 3d, there is lookAt, but how to correctly organize the rotation of the object to the point of contact using IpointerDownHandler?
Help me please!

google the query for you) hold on. how to turn.
and IpointerDownHandler - I think there is more than enough example in the documentation ..
however, to rotate the object in the direction of pressing - I hope not to click on this object itself)) otherwise it will somehow rotate towards itself ..
