Z2M failed start in docker with syntax group_add in docker compose

What happened?

If I use the syntax given in the documentation :
group_add
dialout
user: 1000:1000
the docker did'nt start
load derror in parser ( while parsing a block mapping) at L2C5-L19.C8 did not find expected key

What did you expect to happen?

Search the Docker Compose documentation for the group_add and user configuration example described in the issue. Check the example as a complete Compose YAML document and verify it parses successfully and allows the container to start; done means the documented syntax no longer produces the reported parser error.
