Retrieval of AOT and WV map

Hello, I would like to get AOT and WV map from Sentinel-2 product. Manual for Sen2Cor and web say that it is possible. I read through the manuals and topics here but I didn’t find any conclusion. So, I downloaded L1C product, installed Sen2Cor plugin in SNAP, but don’t know waht to do know. I tried to run Sen2Cor with B12, but with no result. Please, somebody can help me?
