I-751 in Pending - N-400 pending, getting dovorce

[MPS]

I’ve been living in the USA for almost 10 years.

Timelines

2013, I entered the USA on a work VISA
2017, I got married to a US citizen.

2018, Applied for a Marriage based green card.
I already had a valid work VISA and a Job, so I did not apply for a green card until after 14-15 months


2019, Received my two-year conditional green card.
2021, Applied for GreenCard condition removal (I-751)
2021, Received (I-797) which auto extended my Green card for 2 years (2023)
2022, Applied for Naturalization (N-400)

2022 (December), We have decided to file for divorce for personal reasons.
Divorce is not finalized yet. Just started the paperwork.

I believe I’m still eligible to request a Greencard even after the divorce.
But I think I need to rescind my N-400 application

My question are

a ) What are the process & forms to inform USCIS about the current situation of undergoing a divorce when I-751 is pending?
b ) How to rescind the N-400 application, or it's not needed?

Is your spouse willing to go to the interview if there is one before the divorce is final?

I don't think there is a need to withdraw the N-400 before the divorce is final.

Yes, she is ready.
It's an amicable mutually agreed divorce.

All I was looking for was the process to inform USCIS about the current situation.
I’m unable to find which form to fill out to inform USCIS.
