Why is ClF3 considered polar if it doesn't have a partial positive and partial negative attraction?

I believe it's because it's t-bone shaped and the three dipoles don't cancel each other out, causing it to be polar

ClF3 has 2 lone pairs and its molecular shape is t-shaped. Because of the 2 lone pairs, the dipoles don't cancel, so ClF3 is polar.

ClF3 has 3 atoms bonded and two lone pairs which create a total of 5 regions of electron density which denotes a T shape. The net dipole moment would be pointing to the lone pairs making it polar. As for the dipoles of the other atoms in the molecule, Cl has greater electronegativity than the F atoms so the dipole between a Cl and F bond would be toward the Cl (central atom in this molecule).
