It was intentionally used for biasing a common-mode filter, but the ref-currents are so weak that you better just buffer this pin with an external 0.1uF capacitor.

How can I buffer(physical connection) this Pin with an external capacitor?

You connect one side of the capacitor to this pin and the other side of the capacitor to ground.
