Modifying the "WixUI_InstallDir" doesn't show UI

[shreyasg197]

Following https://wixtoolset.org/docs/tools/wixext/wixui/#addingremovingdialogs

I wanted to remove the License dialog, so I copied the source for WixUI_InstallDir and modified as below

I am using it in my package.wxs as below

<Wix xmlns="http://wixtoolset.org/schemas/v4/wxs" xmlns:ui="http://wixtoolset.org/schemas/v4/wxs/ui">

After running the MSI the UI never shows
