Just hit this issue as well - quite annoying - wish there would have been an easier and safer way for applications to share file storage access on Android devices
I did found a solution though to sync my track logs to my local NAS on an Android 13 device. I use FolderSyncPro, and the app has now an option to open a permission for a dedicated folder under /Android/data - you have to type in manually the path (Android/data/com.orux.oruxMapsDonate) and then it appears as a user defined folder, and I can set up sync jobs from OruxMaps data folder to my location of choice.
For those interested, you can find some more information in the FolderSynPro documentation online
