@jomonsam I don't believe you can hide Client Scripts in a bundle. From the Help page titled "Step 3 Select Objects" in the "Creating a Bundle with the Bundle Builder" section:

If your bundle includes server SuiteScripts, you can check the Hide in SuiteBundle box on their file cabinet file records to prevent users who install the bundle from viewing the script files. See Protecting Your Bundled Server SuiteScripts. Client SuiteScripts cannot be hidden.
