I hope you are able to help me.

I've been granted Indefinite Leave to Remain when applying under the EU Settlement Scheme.
I have now a few questions:
1. I didn't receive any card showing my new status. My current biometric residence permit card (EU Family member) is still valid until March 2022 and I've read on Gov.UK in this session:
https://visas-immigration.service.gov.u ... 1636928202
Update, replace or transfer your biometric residence permit (BRP)
If your BRP has less than 3 months validity you may want to replace it now if you need to prove your right to work or rent or you are travelling outside the UK.
You do not need to apply for a replacement BRP if you currently have an application with the Home Office for further leave to remain or indefinite leave to remain.
My question is: Do I need to apply for a new card? I'm probably going away in February 2022 and only back after March 2022, when my card will be already expired so Im guessing I should indeed apply for a new one before I travel correct?
2. What are my next steps in terms of applying for citizenship?
Summary:
Arrived in the UK (from Brazil): Jan 2010 on a Tier 4 visa
May 2011 - valid until May 2013: Post study working
April 2013 - valid until May 2016: Tier 2 general company 1
Jan 2014 - valid until Jan 2017: Tier 2 general company 2
Mar 2017 - valid until Mar 2022: Family Member EU
May 2021 - Granted Indefinite Leave to remain under EU Settlement Scheme
Thank you very much for all your help.
Best wishes,
Patricia
