This will copy-paste the blade file from the Backpack package to your {{ $selectedFileTypePath }}, where you can customize it to fit your needs. Backpack will automatically use the published file if present.

Take into consideration that by publishing (aka overriding) a blade file, you will no longer get the updates for that blade file when you do composer update. For an easy-to-upgrade admin panel, it's recommended that you override blade files as little as possible. In most cases, it would be better to rename the file after it's been published, and only use it inside the Controllers/Views where strictly needed.
