Looks like docker context show is only available since Docker 23: docker/cli#3567.

What's odd is the command exists on Docker Desktop with Docker CLI 20.10.22 ??

$ docker --version
Docker version 20.10.22, build 3a2c30b
$ docker context --help
Manage contexts

Usage:
  docker context [command]

Available Commands:
  create      Create new context
  export      Export a context to a tar or kubeconfig file
  import      Import a context from a tar or zip file
  inspect     Display detailed information on one or more contexts
  list        List available contexts
  rm          Remove one or more contexts
  show        Print the current context
  update      Update a context

Use "docker context [command] --help" for more information about a command.

Do you have an idea why @thaJeztah? Maybe compose-cli handles it?

Yeah, it was one of the things added in "compose-cli", which is wrapping the actual cli on desktop 😔
There's other things as well that work slightly different in that case
