editing android system.img for emulator

I want to edit a few files inside android-30\google_apis_playstore system.img which resides in sdk/system-images. I'm using WSL ubuntu 18.04, I do fdisk -lL system.img to mount with the right offset which returns

Disk system.img: 2.7 GiB, 2832203776 bytes, 5531648 sectors  Units: sectors of 1 * 512 = 512 bytes  Sector size (logical/physical): 512 bytes / 512 bytes  I/O size (minimum/optimal): 512 bytes / 512 bytes  Disklabel type: gpt  Disk identifier: 419B5BC3-59EE-4BEA-AA53-FF67E1D7406E    Device      Start     End Sectors  Size Type  system.img1  2048    4095    2048    1M Linux filesystem  system.img2  4096 5529599 5525504  2.7G Linux filesystem  

and by doing sudo mount -t auto -o ro,loop,offset=2097152 ./system.img /mnt/loop it fails like this

mount: /mnt/loop: wrong fs type, bad option, bad superblock on /dev/loop1, missing codepage or helper program, or other error.  

I have also tried to use simg2img which is said that it will convert the image to a raw image in which I can mount it which yields invalid sparse file simg2img system.img raw.img

Invalid sparse file format at header magic  Failed to read sparse file  

Do you have any idea of how to open or mount the system.img file and edit a few files?
