Missing aarch64 to x86_64 image? How to register /usr/bin/qemu-x86_64-static on arm64 host?

Intro: RPI 5 is a pretty fast board. Its performance is similar to Xeon Haswell with the same CPU frequency.
But aarch64-to-x86_64 emulation image is missing (multiarch/qemu-user-static:aarch64-x86_64)

root@rpi5 ~ $ docker run --rm --privileged multiarch/qemu-user-static:aarch64-x86_64 --reset
Unable to find image 'multiarch/qemu-user-static:aarch64-x86_64' locally
docker: Error response from daemon: manifest for multiarch/qemu-user-static:aarch64-x86_64 not found: manifest unknown: manifest unknown.
See 'docker run --help'.
root@rpi5 ~ $

However, the corresponding user static emulator exists.
For example:

root@rpi5 ~ $ apt-cache policy qemu-user-static
qemu-user-static:

How to register /usr/bin/qemu-x86_64-static on arm64 host?
I can copy /usr/bin/qemu-x86_64-static to docker container myself.
