Hi, I'm new to Datahub, freshly installed it on docker using docker quickstart guide, and now trying the ingestion (pull-based) via UI from the source LDAP. Before doing that I have a doubt: Do I need to install the plugin via command

pip install 'acryl-datahub[ldap]'

or is it pre-installed and I can simply go ahead with

create new source

in the UI? I tried to do, but there was no source "LDAP" and I was using "Other" sources If it requires explicit installation of plugins, how can I do that for the docker image

datahub/acryl-datahub-actions

. Do I have to build it every time when I want to ingest data from a different kind of source?
