Particular path doesn't mount in docker: /usr/local/bin/docker-compose

I need to run docker-compose from within docker container. for this purpose I use following mounting:

volumes:
	      - /var/run/docker.sock:/var/run/docker.sock
	      - /usr/bin/docker:/usr/bin/docker
	      - /usr/local/bin/docker-compose:/usr/local/bin/docker-compose`

docker.sock mounts perfectly. I can create new docker containers from within a container.
But docker-compose isn't mounted (creates an empty folder in docker, instead of the mounted file).

What can be the reason for the /usr/local/bin/docker-compose not to get mounted?

The only specific wsl setting that can potentially affect this is:
/etc/wsl.conf
which is set like this:

[automount]
root = /
options = "metadata"
