How to get parameters from request in cloud functions? Firebase

For Web: (POST Request)

We have:

export const myFunction = functions.https.onRequest((req, res) => {

    const conversationID = req.body.conversationID;
    const currentUserID = req.body.currentUserID;

 return ;
});

Ref : Firestore Read From Values

I read this post and rewrote my code so it works for me.

const functions = require('firebase-functions');
const admin = require('firebase-admin');

module.exports = functions.https.onRequest((req, res) => {

    const conversationID = req.query.conversationID;
    const currentUserID = req.query.currentUserID;

    console.log("conversationID", conversationID, "currentUserID", currentUserID);

    return console.log("getChatGroupConversationAvatars");
});
