• selected module template is used to install module in the module's desired namespace, according to raw manifests and Module CR target namespace
• In case community module template is not to be found locally, return error with hint that suggests to pull community module first
• if user uses --origin=community show error, that he needs to pull it first
• if user passes --origin kyma-system/ CLI should return error with hint not to use -origin flag in case of managed modules
• if --community flag is used , show error that its not supported and community module template needs to be pulled first
