VIN Pin for Wio Terminal?

I’m building a project with the amazing WIO Terminal, but don’t see a VIN pin like the regular Arduino on the pinout diagram.

Can I power the WIO using any of the 5V pins, or is there another way to hard wire power into the WIO Terminal?

I only have 3.7V battery on hand now, I tried it, through the 3.3V pin and GND is possible to power the Wio Terminal, 5V should also be possible.
