I am new to NativeScript and experimenting with it a little via the playground. There are some UIs that i'd like to implement and don't see samples of and I was wondering what would it take to implement? specifically, I'd like to create a bottom navigation such as below, with the middle button.

        </StackLayout>
        <GridLayout row="1" columns="*,*" height="48">
            <StackLayout col="0">
                <Image></Image>
                <Label text="Groups" textAlignment="center"></Label>
            </StackLayout>
            <StackLayout col="1">
                <Image></Image>
                <Label text="Communities" textAlignment="center"></Label>
            </StackLayout>

    </GridLayout>
    <GridLayout borderRadius="50%" width="68" height="68" backgroundColor="#ec5281"
