Add a file upload button to chat screen - react-native-gifted-chat

Question

My RN 0.61.5 app is running the react-native-gifted-chat 0.13.0. Here is the render which is pretty plain:
render() {
console.log("In GiftedChat render : ");
return (
<GiftedChat
messages={this.state.messages}
onSend={messages => this._onSend(messages)}
user={{_id: this.state.myself.id,
name: this.state.myself.name,
avatar: this.state.myself.user_data.avatar}}
/>
);
}
I would like to add a file upload button (which can open gallery or file manager) by the typing text box allowing user to upload an image or video file. How can I do that? I have searched online and gone over the doc but did not find a way/hook to add a button to the chat screen. Many thank.

There is a prop called renderActions() in gifted chat docs. It adds a custom action button on the left of the message composer. I have implemented image uploading button by using this.
<GiftedChat
messages={this.state.messages}
onSend={this.send}
...
renderActions={() => (
<React.Fragment>
<ImgPicker setmsgImgUrl={this.setmsgImgUrl} />
</React.Fragment>
)}
/>
I have created the ImgPicker component by using codes in the expo docs image picker.
