Upload error, failure uploading, exit status 1

I'm using a P-NUCLEO-WB55 MB1355C-02 device. I have "Arduino Uno" as my board and "COM3" as my port. I am on Blink and I clicked upload to see if my device is connected correctly (which the online tutorial I'm using told me to check; this is the tutorial: tinyML Summit 2021 Pete Warden Tutorial: Building a Magic Wand - YouTube). But I'm getting the following error:

avrdude done.  Thank you.

Failed uploading: uploading error: exit status 1

Could someone guide me on what to do with this, please? I'm very new to ML, btw, so apologies for being slow.

The site (https://www.st.com/en/evaluation-tools/p-nucleo-wb55.html) shows an Uno v3 expansion connector, but the board isn't an Uno. The volunteers on the site don't typically watch videos so I'd suggest carefully re-watching the video, maybe even outline the steps it recommends here for connecting.
