[bug]: docker compose completion does not work

[Chucky2401]

What happened?

I followed this video to begin with zsh and zinit: https://www.youtube.com/watch?v=ud7YxC33Z3w&pp=ygUDenNo. And this one to add more features: https://www.youtube.com/watch?v=mmqDYw9C30I.
I would like to load the OMZ plugin docker-compose for docker compose completion but it doesn't work at all.
I made my test on WSL2-Alpine, I tried on a Debian on a Raspberry Pi 5, and same results.

Steps to reproduce

1. Load the docker-compose with OMZP: zinit snippet OMZP::docker-compose
2. source ~/.zshrc
3. Try with completions only:
   zi ice as"completion"
zinit snippet OMZP::docker-compose/_docker-compose

Relevant output

with `zinit snippet OMZP::docker-compose`

Setting up snippet: OMZP::docker-compose
==> Downloading OMZP::docker-compose (with curl, wget, lftp)
##################################################################################################################################################################################################################################### 100.0%
==> Compiling OMZP::docker-compose [OK]


Or with
```shell
zi ice as"completion"
zinit snippet OMZP::docker-compose/_docker-compose`

```shell
Setting up snippet: OMZP::docker-compose/_docker-compose
==> Downloading OMZP::docker-compose/_docker-compose (with curl, wget, lftp)
##################################################################################################################################################################################################################################### 100.0%
==> Compiling _docker-compose [OK]
==> Installed 1 completion

but do docker compose <TAB> nothing happens

If a run zinit update I got this

Updating snippet: OMZP::docker-compose
