SAP Asset Manager official app - Offline maps - pe...

I want to use Offline maps in SAP Asset Manager mobile application. Some time ago I built SAP Service and Asset Manager in the BTP cockpit. Version: SAM version 2305, Android 10/11 (or lover). I installed it on my Android devices and copied a .tpk file (my map). Then I had to go to the permissions (in Android settings) and grant permission to access files.

Apps -> Permissions -> Permissions -> Files -> See more apps that can access all files -> (scroll and find) SAM
|O| Allow access to manage all files
| | Don't allow

So far so good.

But when I install the official SAP Service and Asset Manager from Google Play, the application does not have permission to access my offline map (I cannot grand the permission). In one device, I do not have SAM in the list of applications to grant File access permission. On another Android device, I have a missing option.

Android Settings -> Apps -> Permissions -> Permissions -> Files and media -> (scroll and find) SAM
|O| Allow management of all files    ! the option is missing for this app !
| | Allow access to media only
| | Don't allow

My older SAM built by BTP with an Android API level lower than 29 has this option in Android Settings.

In Android, can I somehow grant the permission even when .apk does not say the permission is required? I suppose the permission has to be specified in AndroidManifest.xml and this file can be distributed only with the .apk? I need to use the official application from the store.
