Need help with extra info to resize partition in EMMC

[pierrep56]

Hello,
I am new here (and gald to be here). I have the postmarketOS edition, and I would like to flash the EMMC with the last Arch image. 
I have the Jump Drive on a SD card and I can boot from it. Also no problem to expose the EMMC drive in my Linux laptop.
Until there all good, but then I become confuse and wnat to be sure I won't make an error :
The wiki instructions says to run cfdisk to resize the partition., this is OK. But I am not sure WHICH partition to resize ?

I can see 2 partitions, the small boot one and a other bigger (Lucks encrypted)

[Moderator edit: Removed image that did not display properly]

Sorry if the question was already answered (could not find it) and sorry for what may be a noob question..... 
Do I need to resize (from the image above) sdg1 or sdg2 ? And to be 100% sure.... Must it be ext2 ? Can it be ext 4 ?
Thanks in advance for any help !

Just flash to EMMC using dd or Etcher or whatever. No need to resize. Arch does that. You'll lose the encryption though.

Thanks, I'll do this . (And sorry for the big jibbrish text in the OP, seems I didn't past the image the right way)
