Add docs for using this package on Android TV and Fire TV

We're trying to use the RN Theoplayer UI package for an Android TV app, but I'm missing documentation on how this package can be used for TV devices.

After a quick test, I ran into the following problems:

The react-native-google-cast library is also required for Google TV / Android TV
The UI doesn't show/hide as expected when using the remote
The slider (SeekBar) is not working correctly with the remote
The button focus state is not clear

The readme states that this package supports Android TV / Fire TV, but I think this is invalid (or I'm doing something wrong).

This is the code I'm using:

import React, { useState } from 'react';
import { View } from 'react-native';
import { PlayerConfiguration, SourceDescription, PlayerEventType, THEOplayer, THEOplayerView } from 'react-native-theoplayer';
import {
  CenteredControlBar,
  CenteredDelayedActivityIndicator,
  ControlBar,
  DEFAULT_THEOPLAYER_THEME,
  FullscreenButton,
  MuteButton,
  PlayButton,
  SeekBar,
  SkipButton,
  Spacer,
  TimeLabel,
  UiContainer,
} from '@theoplayer/react-native-ui';

type Props = {
  uri: string;
}

const VideoPlayer: React.FC<Props> = ({ uri
 }) => {
  const [player, setPlayer] = useState<THEOplayer | undefined>(undefined);

  const source: SourceDescription = {
    sources: [
      {
        src: uri,
        type: 'application/x-mpegurl',
      },
    ],
  };

  const onReady = (player: THEOplayer) => {
    setPlayer(player);

    player.autoplay = true;
    player.source = source;
    player.addEventListener(PlayerEventType.ERROR, console.log);
  };

  return (
    <View style={{ position: 'absolute', top: 0, left: 0, bottom: 0, right: 0 }}>
      <THEOplayerView config={playerConfig} onPlayerReady={onReady}>
        {player !== undefined && (
          <UiContainer
            theme={DEFAULT_THEOPLAYER_THEME}
            player={player}
            behind={<CenteredDelayedActivityIndicator size={50} />}
            center={<CenteredControlBar left={<SkipButton skip={-10} />} middle={<PlayButton />} right={<SkipButton skip={30} />} />}
            bottom={
              <>
                <ControlBar>
                  <SeekBar />
                </ControlBar>
                <ControlBar>
                  <MuteButton />
                  <TimeLabel showDuration={true} />
                  <Spacer />
                  <FullscreenButton />
                </ControlBar>
              </>
            }
          />
        )}
      </THEOplayerView>
    </View>
  );
};

THEOplayer / react-native-theoplayer-ui
