Once that trim is off, use a 14mm socket to free the plug’s pins by loosening a 1/8 turn then pull it down to get it out. Don't force it more than that or you risk breaking the pins. Here is a video of someone else doing it, but please note that he improperly rips the drain plug out and I also would be nervous sticking a garden hose up into the drain like he did.
Firstly thanks for the very helpful post and informative video!

Unfortunately I couldn't get to free the plastic plug's pins. A 14mm socket doesn't fit as it was too small, and I couldn't find anything suitable to turn it to loosen it. I had to use the method in the video, yanking it off with pliers

The good news however, was that not a single drop of water came out!!
