Installing onto ASUS RT-AC1200GU – Installing and Using OpenWrt

I’m trying to get openwrt onto my router, its an ASUS RT-1200GU. I saw git.openwrt.org/?p=openwrt/openwrt.git;a=commitdiff;h=86d019d116c860907c96263ee43425bf637e3bb5 does that mean that my router is in fact a RT-AC57U?

according to this: openwrt.org/toh/asus/rt-ac57u i can use downloads.openwrt.org/releases/22.03.4/targets/ramips/mt7621/openwrt-22.03.4-ramips-mt7621-asus_rt-ac57u-squashfs-sysupgrade.bin ?
