H1B extension with wet reckless - employer doesn’t know

I’ve a wet reckless case from feb 2023. The case is closed and my probation ends in April end. My employer doesn’t know about it yet and they are about to apply for my H1B extension. I’m evaluating if I should be upfront and tell them about it, or should I let them file and wait for it to be approved or to get an RFE and respond to it. I do not want to give this info to the employer if it’s not needed, but I’m also worried if they’ll receive an RFE they’d be mad at me coz I didn’t share this info earlier. I spoke to few Immigration attorneys and got mixed advice. Anyone here who has similar experience? How did you deal with it and what is the right thing to do?
