Does moby support "docker app"?

1

I mean this: docker app from the main Docker page.

I tried enabling docker experimental features, yet I get this:

√ ; docker --version
Docker version 19.03.13, build 4484c46
√ ; docker version -f '{{.Server.Experimental}}'
true
√ ; docker app help
docker: 'app' is not a docker command.
See 'docker --help'
✗ 1 ; rpm -qa | rg -i moby
moby-engine-19.03.13-1.ce.git4484c46.fc33.x86_64
√ ; uname -a
Linux nightwatch 5.10.11-200.fc33.x86_64 #1 SMP Wed Jan 27 20:21:22 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
√ ;

Am I doing something wrong there?
