macOS: Use FontAwesome

Hi,

I have a Xamarin.Forms application with FontAwesome for iOS & Android. Now I
want to use it in macOS also.

I added this to the Info.plist:

    <key>Fonts provided by application</key>
    <array>
        <string>FontAwesome5Regular.otf</string>
        <string>FontAwesome5Solid.otf</string>
    </array>

In my App.xaml I use this:

<OnPlatform x:Key="FontAwesomeBrands" x:TypeArguments="x:String">
    <On Platform="Android" Value="FontAwesome5Brands.otf#Regular" />
    <On Platform="iOS" Value="FontAwesome5Brands-Regular" />
    <On Platform="macOS" Value="FontAwesome5Brands-Regular" />
</OnPlatform>

<OnPlatform x:Key="FontAwesomeSolid" x:TypeArguments="x:String">
    <On Platform="Android" Value="FontAwesome5Solid.otf#Regular" />
    <On Platform="iOS" Value="FontAwesome5Free-Solid" />
    <On Platform="macOS" Value="FontAwesome5Free-Solid" />
</OnPlatform>

<OnPlatform x:Key="FontAwesomeRegular" x:TypeArguments="x:String">
    <On Platform="Android" Value="FontAwesome5Regular.otf#Regular" />
    <On Platform="iOS" Value="FontAwesome5Free-Regular" />
    <On Platform="macOS" Value="FontAwesome5Free-Regular" />
</OnPlatform>

Could it be that the FontFamlily names other on macOS?
I checked that the font is in Resource folder in the macOS project and it is defined as BundleResource.

Thanks and greets,
Johann
