Configuring MQTT Pull Provider for built-in Foreman-Proxy

Problem:
I would like to configure a Remote Execution (ReX) Pull Provider using MQTT, and I want to use the Foreman-Proxy server that is built-in to the Foreman server. (no separate Foreman-Proxy host for economic reasons - it’s a small environment)

I am using this documentation:
https://docs.theforeman.org/3.11/Installing_Proxy/index-katello.html#configuring-pull-based-transport-for-remote-execution_smart-proxy

Step 3.4 is failing:

# foreman-installer \
> --enable-foreman-proxy-plugin-openscap \
> --foreman-proxy-plugin-openscap-ansible-module true \
> --foreman-proxy-plugin-openscap-puppet-module true

1 error was detected during installation.
Please address the errors and re-run the installer to ensure the system is properly configured.
Failing to do so is likely to result in broken functionality.

Furthermore, according to step 3.5, “Lifecycle Envirments” should be configured in the Smart Proxy. But this tab is missing:

Expected outcome:
MQTT Push Provider should be configurable according to documentation without errors.
