Semantic Wikibase on top of wikimedia cpanel app

Has anyone tried to install Wikibase (GitHub - wikimedia/mediawiki-extensions-Wikibase: 🔗 🌐 Github mirror of MediaWiki extension Wikibase - our actual code is hosted with Gerrit (please see for contributing)) on top of the cpanel wikimedia application? Does reclaim hosting support composer and is there anything else I should be aware of when setting it up?
