These are the droids commands you are looking for:

# Install the owut package if it is not installed already (needs openwrt v24.10 or greater)
[ ! -f "$(which owut)" ] && [ -f "$(which apk)" ] && apk update&&apk add owut
[ ! -f "$(which owut)" ] && [ -f "$(which opkg)" ] && opkg update&&opkg install owut

# show packages that are installed on the device but are not in the default sysupgrade firmware
# (ie user installed or added in custom fw)
owut list

# show all installed packages (without listing dependencies)
owut blob | grep '   '|cut -d'"' -f2

# This also shows all apps without dependencies (obviously openwrt >=25)
# The file was generated by running apk update
cat /etc/apk/world
