Wanting to add the adafruit fuel gauge(LC709203F) to my esp32 devices. Can't figure it out

Recently was gifted a ton of components like this adafruit fuel gauge. Tested it on a example and it is really solid, reads voltages well, gives me charging state, and a few other things. I know I could do a voltage divider or something direct to the battery but these are pretty neat and seems to be a little more precise. Would love to include them in the home assistant devices. BUT I cannot find any how-tos on this specific sensor. Wondering if anyone has any insight on it, or if someone can hook me up with a simple way to add it as a custom sensor. I have not done that type of thing yet…and the videos I have found on adding custom sensors don’t specifically mention this one, or adding a supporting library…I am kinda lost.
