Get docker-compose.yml file location from running container?

The answer to this question seems to have changed with new versions of docker-compose.
There is a label "com.docker.compose.project.working_dir": "/var/opt/docker", that points to the directory where I started docker-compose. I have not checked if that is pwd or the actual location of the docker-compose.yml file.

This got me interesting information about docker-compose:

samuel@vmhost1:~$ docker inspect fc440a1afbaa | grep com.docker.compose
                "com.docker.compose.config-hash": "89069285a4783b79b421ea84f2b652becbdee148fbad095a6d9d85aab67ececc",
                "com.docker.compose.container-number": "1",
                "com.docker.compose.oneoff": "False",
                "com.docker.compose.project": "docker",
                "com.docker.compose.project.config_files": "docker-compose.yml",
                "com.docker.compose.project.working_dir": "/var/opt/docker",
                "com.docker.compose.service": "jenkins",
                "com.docker.compose.version": "1.25.0"
samuel@vmhost1:~$ 

I’m running docker-compose.yml configuration version 3.6
