I got the Solution,

import firebase from 'react-native-firebase';
 
import type {RemoteMessage} from 'react-native-firebase';

export default async (message: RemoteMessage) => {
 const GetData=firebase.firestore().collection(`Messages`).doc(`${message.data.Doc_Id}`).get({source:'server'})
    return Promise.resolve(GetData);
}
