Add a widget shortcode in header.php

Hey! I got a new plugin called "Woocommerce currency" it gives me options so I can allow my visitors to change currency. The problem is that I want this widget to be placed in my header. Is it possible?

This is the shortcode: [woocs show_flags=1 width='300px' flag_position='right']

I tried myself, but I just got a white screen.

Would be awesome if you can help me! Ty
