What steps can be taken to restore a missing download module in the module management system?

If a download module is missing in the module management system, one possible solution is to check if the module files are still present in the correct directory. If they are missing, you may need to reinstall the module or download it again from the source. Additionally, you can try clearing the cache to see if the module reappears in the module management system.
