How to mount a system partition in TWRP Recovery for SONY Xperia 1 II?

Hi, I'm solving a problem with the unofficial TWRP for SONY Xperia 1 II.

In my old SONY Xperia Z3 (D6603) phone, I was able to back up: whole system+data+cache+trim area+kernel image.

I don't know how it is in the new phone: "SONY Xperia 1 II", but in TWRP (Unofficial) there is no option to back up and delete the system partition.

Using the tool: "Android Image Kitchen 3.8" from the XDA forum, I unzipped the file: "recovery.img" (the file of the unofficial TWRP) and got to the file: "ramdisk\system\etc\recovery.fstab".

I need to make an adjustment here (mount system partition), but I don't know exactly how and if this file is written correctly against the SONY XPeria 1 II (XQ-AT52) phone.

I need to delete, backup and restore the entire Android operating system to image files.

Please give me any help or advice. Thank you...

File: "recovery.fstab" attached as an attachment.

Tech info: Unofficial TWRP is designed for Android v. 11. In my case: Firmware: ( 58.1.A.5.530-R3B (Service Exchange Unit).

Download link (this version of TWRP):

Note: I'm not a programmer, but I can make basic modifications to commands.

Add this to twrp.flags found inside ramdisk/system/etc/

/super emmc /dev/block/platform/bootdevice/by-name/super flags=backup=1;display="Super_image";flashimg=1;wipeingui=1
/system_image emmc /dev/block/mapper/system flags=backup=1;flashimg=1;display="System Image";wipeingui=1;slotselect
/system ext4 /dev/block/mapper/system
/vendor_image emmc /dev/block/mapper/vendor flags=backup=1;flashimg=1;display="Vendor Image";wipeingui=1;slotselect
/vendor ext4 /dev/block/mapper/vendor
/product_image emmc /dev/block/mapper/product flags=backup=1;flashimg=1;display="Product Image";wipeingui=1;slotselect
/product ext4 /dev/block/mapper/product

Does this modification also apply to the new TWRP (version 3.7.1), as I wrote above?

twrp-3.7.1_12.1-pdx203-UNOFFICAL-240721.img

Because there is already a system partition for backup in the new TWRP, but there is no one for wipe, see the photo below.

I don't know if I did everything right, but TWRP reports an error. See, picture.

Or should I completely replace the original commands with new commands?

Thanks...
