Programatically trigger TouchableOpacity.onPress

I have a use case, where after a file upload I want to open lightbox wrapped inside <TouchableOpacity>

here is my code.

<TouchableOpacity style={{marginRight: ms(10), borderRadius: ms(10), overflow: 'hidden'}}>
    <Lightbox>
        <FastImage
            style={{width: ms(75), height: ms(75), borderRadius: ms(10)}}
            source={{uri: this.props.image.path}}
        />
    </Lightbox>
</TouchableOpacity>

Lightbox does not have any event to trigger open programatically, here is the lighbox I am using https://github.com/oblador/react-native-lightbox

My only option seem to trigger TouchableOpacity.onPress programatically after file upload is done, tried using ref the following way.

TouchableOpacity ref={component => this.touchable = component} with this.touchable.props.onPress(); this gives me an error saying undefined is not an object, when I did console.log(this.touchable) I noticed it is not empty, however when I did console.log(this.touchable.props) it says undefined, perhaps syntax is changed which does not seem to be documented.

Is there any way to trigger onPress programatically?

Thanks.
