Service manual says it is O2 sensor in Bank 1 ahead of TWC. It lists several issues ,but all are related to the O2 sensor.
The other two codes are Oxygen sensing adaptation, Idle range, bank 1 and bank 2 above limit....

running no cats and having run some leaded but it'll always have a cell with no cats in there
You replaced that one 02 behind the cat but you still have to replace the ones prior and the other 4 wire one likely too
