Pixel 3a replacement battery

Hellooo, I noticed that the battery of my Pixel 3a is bulging (spicy pillow).. Being at 37c3 gives me hope that I can replace it on-site. So, does anyone have a matching battery and, optionally, also some tools to actually replace the battery? (I'm also willing to pay some money, obviously)
