This method seems to be duplicated in your project.

The expression $this->capabilities of type array is implicitly converted to a boolean; are you sure this is intended? If so, consider using ! empty($expr) instead to make it clear that you intend to check for an array without elements.

            $isCODEInstalled = $this->getContainer()->getServer()->getAppManager()->isEnabledForUser('richdocumentscode');

The method getContainer() does not seem to exist on object<OCA\Richdocuments\Service\CapabilitiesService>.
