Change in employment during Naturalisation application

Hi,
I have applied online for Naturalisation (have submitted the online application) and have booked for biometrics UKVCAS in December. Few days after I applied my employment has changed as my company was acquired by another company. I now have a P45 from HMRC for the terminated employment and offer letter for the new employment.

1. My question is that do I need to inform UKVI about this change or not?

2. If I need to inform then do I just fill change in personal details form online or is there an email to send all these details along with P45 and new offer letter?

3. Can I submit them at the time of biometrics as well.

What would be the best way to do.
Many Thanks for your guidance throughout this process.
