I managed to implement almost all the functionality I needed, but I am stuck with custom sounds.

What am I missing ?

B4X:
<uses-sdk android:minSdkVersion="19" android:targetSdkVersion="28"/>
Testing on Android 9.0.11

B4X:
Sub Notification (nid As Int, Channel As String, Title As String, Body As String, Priority As String, Tag As String, Sound As String)
    'pro moje zvuky
    Dim rp As RuntimePermissions
    Dim folder As String = rp.GetSafeDirDefaultExternal("shared")
    Dim FileName As String = "novaAukce.mp3"
    'copy the file to the shared folder
    File.Copy(File.DirAssets, FileName, folder, FileName)
    'pro moje zvuky
 
    Dim n As NB6
    n.Initialize(Channel, Application.LabelName, Priority).AutoCancel(True)
    n.SmallIcon(LoadBitmapResize(File.DirAssets, "smiley.png", 32dip, 32dip, True))
    'disable the default sound
    n.SetDefaults(False, True, True)
    'set custom sound
    n.CustomSound(CreateFileProviderUri(folder, FileName))
End Sub

'pro moje zvuky
Sub CreateFileProviderUri (Dir As String, FileName As String) As Object
    Dim FileProvider As JavaObject
    Dim context As JavaObject
    context.InitializeContext
    FileProvider.InitializeStatic("android.support.v4.content.FileProvider")
    Dim f As JavaObject
    f.InitializeNewInstance("java.io.File", Array(Dir, FileName))
    Return FileProvider.RunMethod("getUriForFile", Array(context, Application.PackageName & ".provider", f))
End Sub
