How to use uuu emmc flash *. wic.zst file?

I previously built version L5.10 of Yocto's BSP, which has a mirror file of * wic.bz2, so I used this command to flash.

uuu -b emmc_all imx-boot-imx8mp-ai-robot-sd.bin-flash_evk imx-image-multimedia_imx8mp-ai-robot.wic.bz2

However, when building version L6.1, it generated *. wic.zst. Should I use the same command to flash? Do I need to make some modifications?

refer to the user guide

The following command decompresses zst file and writes into eMMC:
uuu -b emmc_all <bootloader> <rootfs.wic.zst/*>

Thank you very much for your reply!
Does this mean that there is no difference between. wic.bz2 and. wic.zst? For Flash ? Can I understand it this way ?

 they are just different zip format, old bsp version uses bz2, current bsp uses zst, if you use the latest uuu tool, which should support them both
