With the Live images, the OS is in LiveOS/squashfs.img,
which itself contains only the rootfs.img. So there's not
much exploring to be done there without extracting or
mountint the rootfs image.
$ unsquashfs -ll /tmp/iso/LiveOS/squashfs.img
drwxrwxr-x root/root 29 2022-11-05 05:17 squashfs-root
drwxrwxr-x root/root 33 2022-11-05 05:17 squashfs-root/LiveOS
-rw-rw-r-- root/root 8128561152 2022-11-05 05:34 squashfs-root/LiveOS/rootfs.img
Fortunately, the liveimage-mount command from the
livcd-tools package can automate the process of mounting the
nested images pretty easily:
$ mkdir -p /tmp/liveos && sudo liveimage-mount --chroot Fedora-Workstation-Live-x86_64-37-1.7.iso /tmp/liveos
preparing temporary overlay...
b'0+0 records in\n0+0 records out\n0 bytes copied, 0.0001046 s, 0.0 kB/s\n'
Starting subshell in a chroot.
Changes to '/tmp/Fedora-Workstation-Live-x86_64-37-1.7.iso' filesystems are only temporary.
Changes will NOT persist after rebooting.
Press Ctrl D to exit...
[root@localhost /]# command -v gparted
[root@localhost /]#

This is also a pretty simple method. Booting the image can
be done with no setup:
qemu-kvm -m 2048 -vga qxl -cdrom /path/to/fedora.iso
In any case, gparted is not included on the Fedora
Workstation Live images. Though it is trivial to install
within the live image.

Another good option, if you're looking for something you can
toss on a USB drive and have handy.
