The issue of unable to use document type for Mac catalyst project

Hello, I have encountered a question that I hope to receive an answer to. Currently, I am working on a music project for Mac Catalyst and need to enable music files such as FLAC to be opened by right clicking to view my Mac Catalyst app. But currently, I have encountered a problem where I can see my app option in the right-click open mode after debugging the newly created macOS project using the following configuration. But when I created an iOS project and converted it to a Mac Catalyst app, and then modified the info.plist with the same configuration, I couldn't see my app in the open mode after debugging. May I ask how to solve this problem? Do I need to configure any permissions or features in the Mac Catalyst project? I have been searching for a long time but have not found a solution regarding it. Please resolve it, thank you. Here is the configuration of my macOS project: <key>CFBundleDocumentTypes</key> <array> <dict> <key>CFBundleTypeExtensions</key> <array> <string>flac</string> </array> <key>CFBundleTypeIconSystemGenerated</key> <integer>1</integer> <key>CFBundleTypeName</key> <string>FLAC Audio File</string> <key>CFBundleTypeRole</key> <string>Viewer</string> <key>LSHandlerRank</key> <string>Default</string> </dict> </array> Note: Sandbox permissions have been enabled for both the macOS project and the iOS to Mac Catalyst project. The Mac Catalyst project also has additional permissions for com. apple. security. files. user taught. read write
