Grove Shield for Seeduino XIAO Battery Advice

I’m an electronics noob. I’ve just purchased the Grove Shield for Seeduino XIAO. I saw on the video there was a battery attached - is there a guide (video/diagram) anywhere which shows how to wire the battery to the power pads? I assume I have to solder something!

Turns out the answer is yes, to the pads on the bottom of the XIAO board based on one of the seeed videos I saw on the XIAO BLE Sense
