I am experiencing an issue with the Magisk app on my device, which is running Android 14 on the Car platform. Specifically, when I try to launch the Magisk app, I am unable to select the `boot.img` file from the file manager. I have the Magisk app installed, with version `v28` (code `28001`) or `v27` (code `27000`). The device is running on the userdebug version of the Android image. I was wondering if anyone knew if the Magisk app supports the Car platform, and if there is another way to patch the `boot.img` file or install Magisk without using the file manager.
